Can I point out that the price of JAMMA cabs has been steadily on the rise due to the proportion of sledgehammering they keep getting.
You used to be able to buy one for about £50 then £100 now I keep seeing them go for £200+.
Hmmmm, anyone want 9 x ..... no, seriously not in my lifetime.
I started out on a JAMMA cab which I installed MAME into its existing wiring using a JPAC etc, then I got annoyed with the flicker and framerate issues even though I bought the ArcadeVGA card etc so I got one of Frothy's 60-in-1 boards and just enjoyed the heck out of it for months.
The sound is a bit pants on some of the games and the playability is not there on some either but in the main, if you just want a trip down memory lane for about 45 classics out of the 60 advertised then you can't beat the price, in fact, you couldn't cost your time out and the PC etc cheaper - and what's better is they just boot up and that's it - ok, it'll take about 60 seconds to boot but meh, I have some original PCB's that have the longest test cycle ever.
I still have my multi game boards, they are my emergency back up boards for the parties and taking to events, nothing worse than a dedicated Galaxian board failing after 3 hours on a 2 day event - slam in a 60-in-1, set it to one game only and it looks to the casual observer like an original.
Just don't go buying one of those frankencab's no matter how much you think you'll need it - you'll never need 5 spinners, 6 player positions with 10 buttons each, 4 steering wheels and 8 trackballs.
