@ Jeff: Somehow I managed to...
@ Hari, I found it a bit strange that you say the A75 comes with no warranty, as Canon themselves have one listed
here . However it states US and Canada only, and I can't find anything international. Does the store you are planning to purchase it from offer some sort of prolonged repair/return plan? Some might.
The Powershot A75 renders colours very nicely, turns on quickly, and focus is just fine for a camera of this price range, especially with low light AF assist. Picture quality, as suggested by various sites, and by me :P is excellent . I've used the A70 and A60 ( older models ) and the A75 is an improvement over the two, so I do believe you'll be happy with what you get.
The A75 uses TYPE1 CompactFlash, so make sure you get that and not type 2; it won't fit. CompactFlash is more durable and larger then SD. I also believe there's a small price difference between the two. If you're ever likely to get another camera, chances are more likely that the new camera will accept the CF card rather then the SD, which I think are usually used in smaller cameras.
The camera is almost all metal, and it does not feel filmsy or plasticky. It also has some weight, which is pleasant. I think the A series are proven by users, and will work for a while. My buddy still has his ancient-esque A40. As far as I know, it still functions properly.
To add to all that, Canon also offers a nice amount of various conversion lenses, and I think someone offers an underwater case for it.
