Round here, the lenses usually fetch £25-30 each, the enlarger, perhaps £10-20. The Jobo tanks depend very much on what size they are - If they are the 15xx or 2521 with reels, £10 for the 15xx, £20-80 for the 25xx (depending on which reel). The larger print drums vary in value and to be honest, not worth as much as some would like.

Based on what I would expect to pay in the UK, £100 would not seem too excessive, but I'd prefer a colour head. If it is a private sale locally, I'd take a look at the stuff and try to knock him down (start at 500dk)...
