D5500
This is the same enlarger that I am using. It is probably second only to the DeVere 504, that means really really good. If it has all the right parts and is in good enough shape and you have a good lens on it. That could be a lot to ask if you do not have anyone nearby who is qualified to refurbish and or align it. Actually, if it is in good shape, aligning this beast is pretty simple, but that would be the least of your worries.
What kind of light source is avail with it, and are you sure about the neg carrier?? because this enlarger has a very unique approach to neg carriers. It's kinda hard to explain but there is a "cassette" for each "family" of neg carrier sizes.
If there is a chance that at a later time you will be heavily involved in 4x5, then it might be worthwhile to grab this while you can even if you just put it in storage. At this price, it is pretty hard to beat. but only if you are really going to need it in the future.
