I'd say go beseler. I love my 23cII. The nice thing is that some arts (particularly lens boards) are compatible between the 23c and the 45 series, so if at some point you decide that you want to be able to enlarger your 4x5 negs, then the two enlargers are compatible that way. Also, the 23c is a really nice enlarger. It doesn't get as much credit as it deserves, these things are fantastic! I love my 23c, it's great. I do prefer my 45mxt in most cases, but the 23c was my first enlarger, and it is definitely a nice one! The stuff that comes with the durst doesn't grab my attention, except the el nikkor lens. Overall, the 23c would most definitely be my preference.
