I currently use an Omega B5 with a cold light head to enlarge my 35mm and 120 negatives, but would like to get a 4x5 enlarger so I don't always have to contact print my large format stuff. I'd like to get a Dichroic enlarger because of the built in filters and diffusion light source. I've found using a cold light with VC papers is too difficult. I will be buying used off of EBay, and dont dont want to spend more than $500 (I already have some good lenses). I was looking at the Chromega or Saunders 4500. Is the fan a problem in the Saunders? I'd apreciate any advice, thank you.

Grady, I have the Saunders 4550XLG VCCE. My fan has not been a problem. The only thing that I have replaced is a light bulb. Mine is for sale but it will go for quite a bit more then you indicated. This enlarger of mine has modifications to allow sharp and unsharp masking of negatives. Let me know if your budget will stretch.
