Here's the deal. I realize that the OP is not in the US so this may or may not be applicable; but for anyone in the same situation in the US, you really can't do much better than one of the Omega D series or Beseler 45 series enlargers overall. Parts are easily available and not too expensive. Build quality is good, and there is room to grow if you decide to move up to 4x5. In any case, either will do an admirable job with smaller formats. If you are partial to using diffusion type color heads, the Omega Chromega II lamp house works very well with variable contrast papers. Dichro heads are lss common for the Beseler 45 enlargers, but their condenser heads are top notch. I have one of each in my darkrom and I wouldn't trade them for anything - even the much ballyhooed Durst L200. I once had a chance to pick up one of those for next to nothing, and while the price was attractive, the thought of hunting down the extra bits and pieces I'd have needed put me off.
