Congrats on the new enlarger. I am also using the 23, though mine came with a dichroic head. The dichroic head is very versatile and flexible. You have everthing there for color and variable contrast b&w. You also have the choice of condensor or diffusion. I would recommend watching for a dichroic head on ebay or whatever. Make sure you get the accessories so you can use the condensor feature. I still like to use the condensor on b&w. If you don't like the 50 mm lens, get a rodagon on ebay for around $50, you can't go wrong unless someone has dropped it or something. Have fun.
