How about the Alpha Apex 2? I have the Eketlon Model H, is is the previous model of the Neos. If I was to replace it, I would get look at the Gamma 6004 and the Alpha Apex. The Neos is a great machine, and I have been happy with mine for over 20 years...but I probably would seriously look at the 6004 or the Apex 2.
Get a stand alone machine. Easy to push into a corner, and I took mine on the road for many a years. Easy to take apart and move. Just check calibration.
