Good deal. Honestly you should be able to sell one for a good price to help build out your shop.

As for CNC'ing as long as the parts are small the machines won't do too bad. Sometimes you can plan around the registration problem. If the registration problem becomes an issue I'd suggest selling the other mill also and getting a square column machine. If your CNC work ends up outside the scope of spindle quill travel it just isn't worth the hassle. However a little thought and the use of tool holders that normalize cutter length can go a long ways to making the machine usable.

You don't say what you make regularly, but you might consider making a router / bridge mill if the quill travel on this mill is enough.
