A friend bought a '95 Berlin Pro 22 (trem version) earlier this year for around £600. However, I've seen them up for as much as £950, and a store near me had one for £850 a few months back, in cr@p condition.
As Tonemonkey says, the recieved wisdom is that the pre-96 guitars, made before the firm was sold to Gordon Tilley, are the ones to have. I've only played four old Eggles, so I'm not in a postion to offer judgement on that. However, I would say that I wasn't all that impressed with the new one I played at Music Live in Brum a month or so ago, especially as they were asking about £1,400 for it. As we know, there's some bloody serious competition around that price point, and it just did not cut it.
My buddy's Berlin is a very smooth player - fretboard radius is around a 12" and the neck itself is a slim-ish C-shape, if i remember right, and it's in decent, although not perfect, condition. The sound is pretty good, although the Duncan pickups did sound a little bit thin - then again it was being A/B'd with my Warpig-loaded Warmoth! Overall, I have a feeling he got a bargain, as every one I've seen since has been pricier.
There's a decent amount of info on them over here:
