hey guys, im looking at building my first 4 player panel that i plan to attach to a 25" dynamo cabinet (to replace the small, cut-corner metal panel)....provided that i can get my 27" tv in there. i sold my DK cabinet to another forum member who will be pickign it up saturday. my existing 2 player mame cabinet, will be moved upstairs to the kid's playroom. this leaves me with one 4 player cabinet in the family room.
I want 4 players, trackball, and dedicated 4 way stick. i want to have enough room for all the controls, but without it looking too large. my current 2player panel is 12x30 and is pretty comfortable for 2 adults.

i will be taking the trackball from this panel to put in the new one....here is what i have come up with so far

exact locations arent set yet, just a rough idea of spacing. this panel is 18x40..i moved the player 1 and 2 controls each 1 inch closer to the center, which i think i will not do, so i'll probably make it 18x42. does that seem like a reasonable size for a 4player panel on a cabinet this size?
i know that players 3 and 4 would be standing at strange angles, but that's how they are on real 4 player cabinets and to be honest i just dont expect them to be used that heavily.
i am leaning towards that color scheme so that the TMNT characters are color coded properly.
the 3 yellow buttons will be wired up the same as player 1 buttons 1-3 to be used with the 4way stick.(red stick in the picture)
my real dilemma is what sticks and encoder to use. i currently have two u360s in my zakman cabinet, i also have a gutted 2 player x-arcade unit that was in my DK cabinet. i look at it that i have 2 options:
1. move the u360s to the new cabinet, get some sanwa JLW sticks for players 3 and 4 so they match. i can use the u360s for some of the buttons, and get a 2 player ipac or keywiz for the rest of the controls. i can then use the transplanted x-arcade encoder for the zakman cabinet (just set up with a street fighter type layout, and a dedicated 4way)
2. keep the u360s in the zakman cabinet and go with a standard street fighter setup, then buy an ipac4 and some happ competition sticks for the new panel, and dont do anything with the xarcade.
the zakman cabinet will primarily be used by the kids since it will be upstairs, so i'm thinking using cheap sticks in it might be a better option. that way with the u360s in the new cabinet, i can still play qbert. my concern here is that i haven't used JLWs in 8way mode before, i'm not sure how i will like them...but then again they are only for the 4 player games, so it may not matter at all. (i know they are awesome 4way sticks.)
if i have to buy an ipac 2 for players 3 and 4, should i just spend the extra money and get the ipac 4 just in case i want to change something down the road?
is there anything else i am overlooking?
