in the market for a new, decently price and decent quality walk-around lens.

there are a few 28-135 f3.5-5.6(?) on POTN for around 260

are these good lenses?

i was between that and a 17-85 f4-5.6 but i'm thinking i might end up wanting a bit more reach.

and no, i dont want to buy several lenses.
