1) What do you feel is a fair price for a Quality gun?
2) What is the Maximum you will pay for a Gun?
3) Will you pay extra for a Arcade Power Feedback Coil + Power Transformer kit?
4) How much extra would you pay for a Arcade Coil kit?
5) How many guns will would you buy?
6) Would you prefer to have a Gun with Arcade Recoil built in?
7) Would you prefer to have a Gun sold without feedback - but leave room for Coil Kit?
8 ) Would you prefer there is no recoil, and no recoil kit available?
9) Would you prefer very cheap guns without features?
10) Would you prefer Expensive guns with ALL features?
11) Would you prefer Medium price gun with some features, and is upgradeable later?
1) I'd say that $60 is a fair price for a high quality, accessible gun. If it comes without kickback, I'd say $30-40 would be the sweet spot.
2) If we're talking the Slikstik Tornado of light guns, I'd be willing to pay up to $80 for it, assuming it truly was arcade quality construction (including kickback) with PC quality precision / features.
3) If the base gun is reasonably priced ($30-40), I'd be willing to pay extra for an arcade-quality kickback kit.
4) Depending on the base gun price, I'd say between 50-75% of the price of the gun would be fair. If the gun is cheaply priced, the kit can be more expensive. If the gun is more expensive, the kit should be cheaper.
5) Two
6) It depends on the price. If it stays in the $60-80 range, I'd buy it with kickback. If it puts the price more in the $100 range, I'd rather buy the gun for $60 first and get the kickback kit later for $40 (or vise-versa).
7) As stated above, it depends on how much of an impact the kickback has on the price.

No. For me, quality kickback would be one of the major factors in choosing a new light gun model over the ones currently available.
9) No. As stated above, there are already economical gun solutions on the market. I'd prefer a new gun to be a more premium option.
10) I think it's important gun offers good tracking, study construction, good kickback, and a foot pedal for Time Crisis. However, there are some features I think are less desirable, lots of buttons on the gun itself, laser pointers, etc. I'd prefer a nice clean design like an actual arcade gun over one that is covered with buttons for extra functions.
11) I think it would be a good idea to offer some features, like the foot pedal, and possibly the kickback kit separately if it keeps the initial cost accessible.
As for my own ideas, I think that if a kickback kit is avalible, it should involve disassembling at least part of the gun to install it, because that would ensure a clean, arcade-like exterior. A premium light gun IMO should offer something as close to the arcade experience as possible, and having a clearly visible "kickback cartridge slot" would detract from that.
Speaking of the gun's design, it should be clean and durable, and possibly even offered in multiple colors. Aside from the trigger, I think there should only be no more than two additional buttons (only one additional button would be preferable to me). Also, a solid, beefy gun like the Desert Eagle would be a great design for getting the "arcade feel," since many arcade guns have a slightly over-sized feel.

Or, if it's a truly fantasy inspired gun, then perhaps the Samaritan from Hellboy would be good for inspiration. However, while I love a beefy-feeling arcade gun, I wouldn't want things to get
too crazy.

And lastly, there's the Nerf Maverick Rev-6 (this one was re-painted by custom action figure guru Jin Saotome).

Also, I think it'd be a good idea to offer a sturdy, arcade-quality foot pedal, possibly one that has mounting options if someone should want to bolt it to their arcade machine. It'd be great if the gun included a plastic pedal, but what would be even better would be is if there was a heavy-duty "arcade-grade" pedal made of metal available, possibly separately at a premium price. If such a pedal were available, it should definitel have the mounting options. I don't know how much it would cost, so I won't pretend to know what would be a reasonable price for it. But it it's expensive, there should be a cheaper, plastic alternative too.
