Advice on a 4x5 enlarger

I had a Beseler 23c III with a Dichro head and kept it for 4 days, then sent it back to the place I purchased it. It was absolutely junk, and after talking with a very friendly gentleman at Beseler, I was happy I sent it back. I'm just sorry that I had ordered it to start with! I am waiting on a new Saunders/LPL 4550 XLG with the Dichro head. Hopefully it will be much better.
