hi all. I am new to apug, and having a darkroom with an old soviet upa-150 enlarger at home. It is very hard to use it, the moving parts are vry hard and not so smooth, the lens is also not clear. therefore I started to look for a new enlarger. the story starts here: I found that the price range for a enlarger varies from free to a thousand dollars. many photographers threw away their old beatiful enlarger for just a few dollars but now I cant find them!! then, I found a durst m670 for just 70 dollars. but there are cons: the lens is rogonar 50mm f:2.8 but has fungus, there is no neg. carrier, there is no swing out red filter (it is evry important for me while using my upa). it needs a new lamb. it has timer+exposure meter. the overall condition is seems good with very smooth movements. but the cons made me not to buy, yesterday. I need two advice, one is very general: I always print b&w, and will. color head is an advantage or disadvantage? Can they change the film's contrast? since while I try to prind the ngs with clouds to my constant contrast papers, the clouds cant seen.. the second, are the swing out red filter and the neg carrier hard to find? and how much they can cost? I think here is the only place in the net that I can find an answer regards from Turkey!!
