Seems clear that prices for certain used Pentax lenses have popped up quite a bit in the last year or so. Do you think that prices are higher to stay, or is it a bubble (like might be happening in the housing markets in the UK, US, and Australia)? Thoughts?
My feeling is that prices of used lenses were low due to people switching systems back when the *istD was an expensive competitor to the 300D and D70. When the *istDS came out with backwards compatibility with older lenses, prices went back up again. They'll stay high for as long as (a) new Pentax primes in the same ranges are scarce, and (b) K-mount DSLRs continue to sell well.
