Well, I'll go against the majority here and say to the change-over --- maybe?
I kinda got a suspicion that your Atlas is the change-gear version, and it may be in need of some work also .. hence the reason for considering this, and in that case I can see some justification in this... a gear box and clutched power feed, plus a tight feeling apron, crossfeed, tail stock, etc could be a pretty big draw to me.
Cost-wise, that is no steal price, but is certainly reasonable, if it is really low use -- I think HF's is the cheapest and it $750 ish (I think!) ENCO's is $850, and Jet's is even more.
If everything seems to be going well, you have obviously overlooked something........
