5x4 enlargers are rapidly going "out of fashion" especially here in the UK! I picked up a LPL 7451 (colour head), wall mounting kit, 2 diffuser boxes, transformer, ALL negative carriers and 4 threaded lens panels from a dealer for 500 UK pounds. The enlarger had seen very little use and parts are readily available as it is (almost) identical to the current model!! The LPL is very stable and despite a noisy cooling fan, shows minimum vibration!! Well recommended!!
