I got a frenz who is very stingy and wants to get a new camera to replace his Canon 350D. I recommend him the KR which is on sales at Sitex @$699. In the end, he never buy and the reasons he gave was because he think Pentax stuffs are difficult to find and he also thinks Pentax external flashes cannot make it..
The actual Pentax flash units themselves are ok, if a little expensive, but the P-TTL system is indeed a little bit on the cannot-make-it side. But I do have confidence that Pentax will get around to fixing it.
