You got a steal of a deal there! It does look like an earlier model of the same drill/mill I got. I've been very pleased with mine so far. It does have some limitations like the round column, but as long as you know about that and set your machine up with this in mind it hasn't been a problem yet. I think VZ put a pic up in my thread on how to attach a digital caliper to the downfeed. I still haven't done this yet as I found I like the digital caliper and have been using it so I need to get another one. For your down feed, I've been writting down the number I stop on when I lock the spindle. When you go to adjust it again you'll find the dial will no longer be where you left it, but if you bring it back to the number you locked it in at all seems good. Usually if you don't, the spindle will drop 1/16" or so because the hand dial turned to get the pressure of the spindle ram off of it while the machine was running. There's usually good deals on ebay for end mills. Just be patient on finding the right auction and don't get in a bidding contest with someone over them.
