Go for it
I have a 45-VXL I got off ebay for $250, and it arrived in great shape, amazingly. It has the motors for focus and height. It's a great enlarger, really pretty excellent overall. I've used the 45M-series extensively in the past and the VXL is defintiely better. Agreed, alignment can be fiddly but if you are patient it's not bad, really. I use it with an arista cold light head for B&W and a Minolta/Beseler 45A head for color (which I think is the best of the beseler color heads, easily. And they are dirt cheap these days, on ebay. ). Overall, I think it's the best choice in 4x5 enlargers that are reasonably available, reasonably priced, and with good parts and accessories options.
