This was a week or two ago so I dunno if they're still there, but at Micro Center they had a pile of old ISA wireless network cards back on the discount/stuff that got returned table thingy. Was like $80, so they're not that cheap, but if these are the kind you can get serious range with, it'd probably be worth it... They were some brand other, I didn't write down the brand. So I dunno if they're Linux compatable or not. If not then they're kinda worthless to us... Anyway, someone who's interested in such a thing, have at it and report back to us. ;) (Actually, I think I may take another look myself...)
