Want to go back to a Canon Powershot, which one?

I used to use a Canon a710 IS and it was fantastic, everything I needed and took good quality images. .. And the current small digital cameras are amazing I'm sure but just have too many features for me, unnecessarily high image quality for what I need, high price...etc

SO my question...

I would be perfectly happy to go back and buy an a710 IS on eBay for peanuts and use that however I'm interested in maybe upgrading slightly but keeping the same nice compact yet tactile size as the a710(Roughly) and keeping the simplicity and usability of the a710.

I'm open to any other suggestions as well.

My short answer is that the A720 IS (https://www.dpreview.com/products/canon/compacts/canon_a720is) and the second S110 (https://www.dpreview.com/products/canon/compacts/canon_s110, not the first one!) stand out to me as the best overall quality-and-value combinations among older models from somewhat different eras--the S110 obviously being much newer, more capable, and more expensive.

The long answer: I bought an A570 IS, mainly for my wife's use, right around the time our younger son was born, which is right about when it came out. It was a great camera, but eventually died. It was so liked that my parents bought another one (used), and I later bought one used to keep in my car.

And yet, from that era, the A720 IS arguably offered more capability for not much more money. More than once I regretted not getting it instead. But I do go back and forth on that. IIRC the A570 had a couple of advantages.

Also, there was the somewhat uncommon A650 IS, which had a somewhat larger sensor. That should be another step up, if you can find one in good working condition.

Since then we've had a bunch of Canon compacts, including the SX240 HS mostly for my wife, bought new about when our last child was born, an SD4000 IS bought for me as very pocketable option, plus the S95, S110, and very recently S120. We also bought a Canon compact for our older son, the model escapes me at the moment.

At this point I don't tolerate well any camera that doesn't have a raw file option. The S-series models give you that, plus a somewhat larger sensor and somewhat faster lens. The S95 has a CCD sensor and a 28-105mm-equivalent lens. The S100 moved up to a CMOS sensor and 24-120mm-equivalent lens, but by many accounts the lens had bad quality-control issues that harmed optical performance. The S110 was basically an S100 with a corrected lens. It also has a touchscreen, which I like more than I expected, and wifi--I can connect it directly to my phone and wifi over my photos. The S120 keeps all that and moves to a slightly faster 24-120mm-equivalent lens and a slightly better sensor. But my sense is that eBay prices for a good S110 from a reputable seller are a lot lower than comparable S120 prices.

What about the G series? IMO they were always big, clunky, and expensive for what you got. I realize others disagree!
