i got an atlas drill press for £40 on ebay last year and not long after i saw one for twenty odd quid (i can't help meself but keep looking even when i've bought). as someone above says, they're usually 'collect only' so prices vary massively. do make sure it takes an MT chuck or quill though if you want a good bit of versatility.
I got mine on Ebay for £35 and spent £40 in fuel fetching it!
