About to take the plunge at long last and buy my first D-SLR, but having thought I'd made the decision now find myself in a pickle and looking for advice?

I'd decided to go down the K10D/GX-10 route, but having recently read a few reviews of the K200D am swithering again as deciding what to buy - The prices of the three models are pretty close, and the K200D seems to be very close to the K10D/GX-10 in terms of spec. The GX-10 seems like an even better buy with the extra warranty and cashback offer on at the moment. Is this a no-brainer, or am I making hard work of it?

Cheers
