if that was the case, then many brands would have died long ago, but people gave it a try, and it was good, the response was good, the brand improved..
i have used, k100d, k20d, tried a lot of other models before.. the k100d era was really value for money already, now they are giving much more features for your buck..
shake reduction, excellent lenses from the brand itself that are considerably cheaper (prime-wise at the very least) , feature-laden, weather sealing even on entry level.. these are things that other brands cannot offer. of course pentax has its cons. all the pentaxians here in the pentax section would gladly tell you that the brand is not perfect - something that i'm proud to say, we are pragmatic and honest.
why don't you drop by the pentax section and check out, i think the price of k7 is mentioned and relatively rigid because of the good effort of the current distributor (emjay).. i'm not saying that pentax is the best brand, it may never be the best brand, but what i'm saying is that it should be given a go, because it is a lot of camera, for the price. that i dare say.
