These are some in-general tips I am posting to help you guys find some cabinets and help reverse the increasingly negative opinion the general arcade community has about mamers.
#1. Don't ask for pictures of FREE cabinets or games. The person is already giving the machine away free. If they had pics they would have posted them. Just go get the freaker if it is in your range, otherwise ignore it.
#2. Do not contact people asking for FREE cabinets. Local posters on RGVAC and other boards are a good source for empties, but I instead suggest a short email asking if they have any games for sale.
#3. At this point I no longer suggest posts asking about free or cheap cabinets. A better post would just be "Looking to buy project games near INSERT LOCATION".
#4. Do not, I repeat do not "flake out". I don't know why, but arcadecontrols.com and mame guys in general tend to have a huge "flake out" rate. They say they are coming a certain day or time, and then don't show up. You alter your schedule so you can meet them and then they mumble and don't buy anything. They request changes to a cabinet and then vanish off the face of the earth after said changes are made (you KNOW who YOU are).
I actually raised my prices on empty cabinets because it was no longer worth my time to stay home all day and have a chance that someone MIGHT come over and then they MIGHT give me $20. Not worth my time, not worth the time of other people either. I always have a lot of cabinets because I know a lot of other collectors and I grab their dumpster bound stuff.
#5. Be sure and check klov.com and see what a cabinet looks like to avoid buying an unsuitable cabinet, or wasting someone else's time because you didn't realize that Pole Position was a driving cabinet.
#6. No one has free or cheap 4 player cabinets anymore. No one has free or cheap mortal kombat cabinets anymore. You guys drove the prices on those sky high to the point where the gutted ones sell for as much as ones that have games in them!

#7. Be sure and have enough straps with you to tie down whatever you buy. (Really only matters if buying more than one game).
#8. Have fun!
