I use a salzman enlarger I picked up for scrap, It will go to 11x14. but use it for 8x10 and smaller. use a 300 5.6 rodagon enlarger lens on it that I traded for. If you can be patient, a machine someone wants to get rid of will come up for sale, You can use a 355 g-claron or 360 apo ronar for both camera lens and enlarger lens to save $$$, an apo-graphigon lens by rodenstock is also a good choice. A 16x20 enlargement is stunning as you only have a 2x enlargement factor. The real problem is trying to find the grain to focus with! I love contact prints as well, but there are times I want to crop and with a larger neg, there is plenty of extra enlargement factor built in.
