Amazon have a good returns policy. Worth a look?

See post 4

Just don't expect more than a 1 year warranty with them....

I'd recommend taking a look at the classifieds. On the whole prices there are reasonable and Pentax lenses (or 3rd party lenses in PK mount) hold their value rather well so you could get a good deal and if you don't like the lens sell it on without much financial penalty (unless you deal with one individual who likes to charge top dollar [as he can justify it] yet query everyone else's prices)

Welcome to the World of Pentax

Have you enquired at Camera solutions in Chester - they are a pro dealer but I am not sure if they carry a stock of limited's

Oh yeah - Hello and welcome

SRS ,excellent service and knowledge of the products they sell, fair prices and it is also worth checking their used stock, which comes with 12 month warranty also they have an Ebay outlet that is worth a look. as mentioned before the sellers on this forum on the whole are honest and upright citizens to deal with , at least that is my experience and i have bought lenses on here with no problem at all. having used the limiteds i would say you would be extremely unlucky to have a problem with one, the iq is superb in my opinion, the only reason i sold them was i found changing lenses a chore in the end and went back to zooms.
i also think as a consumer you have a 2 week period in which you can change your mind on anything you buy from a retailer anyway.

They certainly had some in the window 18 months ago
