how does these two compare?
I have just gotten M85/2 and I'm really liking it!
I have found some deals on Ms 100/2.8 and 135/3.5. I'd probably prefer the 100 but I'm afraid that it'll be too close to 85!
135 is for tempting price but I'm bit nervous with f3.5 and MF....
any opinions/suggestions?

Peter I have both and have no complaints about either. I got the 100 because it is fairly fast and doesn't suffer much from CA wide open (compared with my K105). I got the 135 before stumbling on a FA135 at bargain price.
I don't think there's much difference between them in terms of performance - I'm happy to use either. They handle similarly. They're both very useable open wide (I wouldn't describe either as soft'), and sharpen up a stop or two in, producing excellent results.
In your position I would just decide which focal length I wanted. The 135 is usually cheaper, one of the best bargains available among old Pentax lenses, and it has a built-in hood.
Stopped down whether you will get better results than from a DA50-200, say, is slightly moot: my experience is that centre sharpness will probably not be that different at f/8, but these old primes will give you reliable sharpness edge to edge, whereas all my telephoto zoom lenses suffer from some greater or lesser degree of decentering, at most focal lengths. So I definitely prefer these little primes for landscape or architecture stuff.
I love their lightness and compactness - and I realise that my M135 gets more use than the FA, just because it is lighter to carry around. For street shooting, family shots or sports of course the lack of AF can be a pain.
Hope that helps.
