Seems like there's quite a few powershot models. I'm getting one for the S/O for Christmas and I'm not really sure which one to get. Based on these at CC: http://www.circuitcity.com//ssm/Point-and-shoot/sem/rpsm/catOid/-13062/N/20013061+20016941+40000857+20013062/link/ref/rpem/ccd/categorylist.do?WT.mc_n=584507&WT.mc_t=U&cm_ven=PAID%20SEARCH&cm_cat=ADVERTISING.COM&cm_pla=CATEGORY%20-%20IMAGING-%3ECLASS%20-%20CAMERAS&cm_ite=3222%20PURCHASED%20KEYWORD%20-%20CANON%20POWERSHOT&cm_keycode=584507 I was looking at the SD1000 7.1 because it looks to be a smaller size then the A series with not much price difference. Any suggestions from OT experts? thanks.
