My wife has an enlarger that is about 5+ years old. it is a Beseler - Cadet II - model #3502. If anyone is fimiliar with this model please chime in. It has not been used for awhile now and id like to see if i can get the equipment back up and running. is it cheaper to take it in and have it serviced or buy a new one? when my wife developed pictures a few years back she always got frustrated because the pictures would have what looks to be a scratch in the same spot every time. so i realize it could be a scratched lens or something of that sort on the enlarger or the camera, but is it cheap to have these enlargers serviced? is it a waste of time?
