I have a canon A80 that i bought a few years ago and paid a good coin for it... and also bought my ole lady a canon A400 and they both take awesome pics no matter what resolution they are in.
The only drawback that i wasn't aware of when i got my A80 is that if you cannot take a few shot is rapid procession . The A400 you can do that but the main reason that i bought the A80 is that the lcd screen can be turned in any direction needed instead of just being a fixed screen.
I have had both of them for a few years now and have never had a problem with any of them.
Now here is one thing that you might wanna look into ....battery support/life !
I went for the replace battery type cause if i am ever anywhere that doesn't have electric and the batteries go dead i can just put any type of batteries in it and go ! I dont have to worry about looking for a place to plug it in and charge the batteries.
And try and stay away from any kind of sony product...they take great pics but if you need anything expandable for it you HAVE to buy there products not just any type of memory card, batteries ...whatever is need !
Before you do buy one go here

Just my 2 cents and sorry for the rambling !
