kinda want to get a mister fpga but it seems like all the addons pushes it to over $300
@proto to make use of everything i'd need a cooling system of some kind, a powered usb hub and at least one of the i/o boards
still adds up
@DarkWitchClaire you can power a 5v fan directly off the arduino headers (mine's actually running off a 3v3 pin for quietness)
and the usb hub I use isn't powered and hasn't been an issue 
@proto i'd probably need something powered if i want to use my arcade stick, and definitely the sdram and i/o boards if i want to experiment around with it more
@DarkWitchClaire the only addons you "need" are an SD ram board and a USB-OTG hub for your input device
it's still certainly not a cheap thing
