A tip: Go to APUG.ORG's classifieds or http://www.photo.net/gc/view-category-multi?primary_category=Large+Format
and simply ask if anyone living within x miles (kilometers??) of your location has a 4x5 enlarger to sell.
I purchased a Saunders VGGE from someone three hours away. Cost $250, including an old enlarging lens. Worth the drive to pick it up!!
Many enlargers are sitting around because they are too bulky and somewhat finicky for shipping, and they languish, awaiting an opportunist!
