What's the opinion on compact digital camera best value under £100? Or much better value at higher prices?
I tend to leave my SLR behind on some excursions and a pocket compact would be handy. Low light for interiors and good close up for details - for when snooping around museums, country houses, shops etc.
Ah, these amateurs who rush out and buy expensive tools...
Anyway, I think you requirments may present a problem; in the present era, mobile phones at one end have killed the cheap compacts - why carry a cheap compact when your smartphone has built in instagram?
At the high end, the digital SLR continues its reign. For those that find digital SLR too big, but want the quality, there's a new world of "mirrorless" cameras. These are not cheap - the lenses and sensors are the pretty much the same size, quality and price as a DSLR.
The upshot of these changes is that the high quality compact market is dead. There are a VERY few good spec compacts, mainly aimed at being a professional or enthusiasts "second" camera, models like the Canon G15 or Nikon P7700.
You specifically mentioned low light - I think you will be disappointed by ANY small sensor camera; one area where DSLRs are great (and have been for a long time) is low light capability; it's the simple physics of large sensor pixels gathering more light.
Photographers now deliberately ADD simulated grain to rock concert shots, because the perfect sharp picture the cameras (actually) take don't have the right "feel" to them!
So I'd second the notion that a second hand model from an earlier era may be the best choice. I happen to own a Panasonic TZ8, and its optical capabilities are pretty good, although low light can be grainy. It also has less good ergonomics than the Canon models (I note that Panasonic finally changed the shape for the TZ18 and 20 models).
But, to repeat; given the shots you'll currently be getting in low light from your SLR, you are almost certain to be disappointed by the shots from a small sensor camera.
I would recommend borrowing one from a friend for a trial before splashing the cash.
