hey, from one starving student to another i understand yr plight. i recently broke an ste for spares (most parts still available if anyone's in need of anything) for my main machine tho the PSU wasnt working on that machine so it would be no good to you. anyhow, the good news i wish to bring you is that someone is selling a pair of st psu on www.ebay.co.uk (just enter a search for "atari" and theyll show up) for only £4.99! bargain eh?
hope i could be of assistance
go check it out now
