I have been thinking about starting to do my own 4x5 BW printing and thinking about bidding on a used Beseler 45MCRX enlarger w/ color head.

My questions are:
1. Does it matter if it has a color head if I plan on printing BW?
2. What questions should I ask the seller about the equipment to ensure it is in good working order?

Thanks in advance for your help.
