Kaiser offer the most felxible, and most reliable source of enlargers. The black and white ones are condensers. However the clever thing about the range is its modular nature - you could start with a basic one, and later on change/upgrade pretty much any feature such as colour head, MG head, base board, column, wall mount, etc etc. It's a very impressive range.
They range from £400 - £1249 - So, similar to lower end Digital SLRs........ie - Good value, especially considering they are virtually hand made.
People should buy them - otherwise, one day, everyone will be moaning here about how Kaiser stopped making them!
