I've got one of the Epson 580s. It's not a bad printer; it is a tad noisy (but that is a issue with most of the Epson Stylus printers). It is USB only and only for Win98 or WinME (and you will need the updated drivers from the Epson site for ME). (The driver install program checks for OS and won't let you install it on Win95 - I tried 🙁 )
Cartridges are about half the price of those for other machines - not available everywhere, but OD routinely carries them.
They have been running about $60-$70 at BB. I got mine about 4 months ago when they had rebates on them, so I paid about $45 bucks for mine, plus $25 for the USB cable.
