What do you guys think of this camera??? I love the ability to selet the shutter speed below 1 sec (unlike my current SD400), bigger megapixel rating, more modes...you think its worth it to sell the SD400 and pick up the S70? I can pick one up on eBay for like $250. I also like the ability of different lenses (nothing like an SLR or anything).

What do ya think?
