Thanks again to all who replied, and I hope you are having nice holidays!
I'm still on the fence about what I should get next. Ideally I want something that can record in RAW, but that has more than 12MP.
My SX150IS does quite well, until you compare it to "real cameras". At ISO 200 and slightly under-exposed compensation (to keep from blowing out brightly lit daytime subjects)...at the pixel level it is just very coarse. It's fine for 11x14 or especially 8x10 and smaller at either 240 or 300 ppi...but if I ever wanted to print larger than that, it would be marginal quality. I've done 16x20 images in the past at 240 ppi, but that is absolutely as large as it can go, and the quality of the noise and artifacts (even after much processing) is less than I would like.
Do any of you have an opinion on the M-4/3 Panasonic DMC-GX1? I notice it's been replaced by newer models that cost a lot more, with rangefinder style EVF's for like $750 and up (apparently jumping on the Fuji/old school rangefinder form-factor bandwagon...)
It seems to me that if a GX1 could be purchased for $250 body only, or $350 with a lens...that would be ideally what I'm looking for.
