"I could get the Samsung GX-20, with a 18-55mm kit lens (I believe it's the same as the K20D kit lens) for about $700 USD - a good deal lower than the price of the K200D"
My K200 (body only) was about $700 Cdn back in March.
I'm sure the 18-55mm would about even that out with exchange on the dollar.
"out of these, the samsung gx20 is clearly the best camera...it used to be around $1400-1500 when it came out (so it kinda belongs in the 40d/50d/d90/d300 league)...nowadays its going for about $750-800 CAD with the kit lens "
I'm kind of lost how the exorbiant price puts a cam in the league of others or how it could "magically" just drop in price in such a short period of time.
I "might" take that as a HUGE indicator/red flag myself.
"to me, things like battery grip arent that important (gx20 should have a good battery life)...but for k200d, spending $30 on a battery grip is a no-brainer "
I use good rechargeable AA's in mine.
I have two sets actually.
I see no need for a battery grip...awesome batteries they are.
"So, K200D or GX-20?"
You asked...I answered....."K200
