Dear friends,
I own two Canon bodies (5D mk2 and 7D) but know absolutely nothing about the compacts.
I would want to buy a compact to make timelapses without killing my two reflex bodies too quick 
Timelapses of clouds, of sunsets, riveing in the car and people moving in town some ideas I have.
The problem I am having is that I cannot seem to find recent models of compacts which support the CHDK fw .The ideal for me would be some 6 9 months old model which I could find on ebay used.
Thank you in advance for your kind replies.
Canon release new compact cameras twice a year - in Jan/Feb and Aug/Sep.
This link will give you a good idea of when the different models were released plus you can click on each camera to see the specs -
http://www.dpreview.com/products/canon/compactsWhile many of this years models are being worked on (SX220HS, SX230HS, A495 to name a few) they are still in development and may not be fully implemented and stable for a while. I think funnel has a pretty stable version for the SX220HS; but only for one firmware version so far (if you get a camera with the other known version you will have to wait).
Support for last years models is much broader, my ports to the G12 and SX30 are pretty stable; but I may be biased

I'd suggest looking at what cameras from 2010 best meet your needs feature and price wise then checking how well supported they are with CHDK.
Phil.
