After all the advice, and much prayer, I have made my decision. I just purchased a new A550 with the 18-55MM SAM kit lens that came with it (and got it for less than the 18-250 was going to cost me). It is definately has a better lens than the original lens that came with the A200. It will take me a while to learn the new options and adjust, but I feel that this will let me take better photos using the lenses that I have and be able to buy the "all in one" lens at a later date after I can sell the A200. thanks for all your help (so far)
Congrats, Joe, I'm sure you'll be very happy with your new purchase.
Look forward to seeing some shots in POTD.
I see you're still hankering after that all-in-one. I'd be interested in knowing your thinking on that one.
