I had a Rollei Prego 115, it was a nice camera. The Classic 120, every time I bid on one it sells high, every time I don't it sells low. I still keep trying, though. I liked the T4 (non-zoom), but at the time I had it and the price I could get for it, compared to what I paid for it, I really couldn't justify NOT selling it. Right now, my favorite is the Lexio, but the Olympus XA3 (close enough to a P&S for me) is a contender for my favorite tiny camera. I think that I took maybe my best photo ever with the XA3 a couple of weeks ago.
I'm pretty impressed with the Samsung Maxima 1350Ti that I bought for basically nothing, but it's slightly too big to be a true pocket-size camera. The Canon Z135 is nice too, and usually a bargain, but once again, it is a little on the large size. And unless shooting 800 ASA or faster, the long zooms on both of those are too slow for hand-held stuff. The Z135 is very nice for macro shots, though.
I am looking forward to trying the little Leica, and it should be here in plenty of time for the upcoming holiday, I hope to get some good shots of a nice roasted turkey and some pumpkin pie. 🙂
