The most I've spent for a single dev item is $258, but I'm sure there're some of us who have spent more than the price of a cheap car! Any currency: http://www.xe.com/ucc/
There may have already been a thread like this, but it's long dead I believe, so there shouldn't be any harm in this one . $325ish for the TEST PS2. I'm not much of a development person - I'm more interested in prototypes.
Ode to Saturn $250 for a Saturn Sophia Programming Box and Genesis controller with a red switch. Sold it for the same price about two months later. I was suprised I didn't regret it at the time (nothing meaningful I could do with it) but lately I've been wanting it back... ~Krelian
Errr.... about 75GBP for a Psy-Q Saturn set (ie, Japanese Saturn modded with NMI cable and Virtual CD board + Psy-Q cartridge)
That's not a Genesis controller if it came with the Sophia - it is a proto Saturn pad!!!!! The one that came with the Sophia.
Alas: Regret. Sorry, should've been more specific: It was shaped identically to a Genesis controller. The more I think about it the more I wish I kept it... damn you Mark30001 for reopening old wounds!
