Need Recommendataion: Powershot SD series

[EOS mE]

hi guys and gals.. this is my post here. i need some recommendation on which powershot to get. wify and i go out to eat on the weekends and she loves to take photos of the different food we ordered so she can do a critique on her blog. before we just use my sony ericson i710 phone to take the photos, but now she wants a smaller camera than the G6 we have.

before the SD600s came out.. we had originally wanted to get the SD500... then opt for the 550. but now the 600s came out.. wify wanted something newer depending on the price.

so between the 3, which ones would you recommend and why?

SD550
SD600
SD630

Thanks.

550 can be found cheap. The 630 has no view-finder when the 600 does. Which is more important to you?

I'd go for the 630 if you dont mind not having a viewfinder. You know, the 700IS is only a few bucks more ;-) hehe

humm.. i don't think wify will need a viewfinder. it's going to be her P&S. now just need to find some hot deals..
