Personally, I like #2 the best, although #3 has some really good points to it. I don't like the really long category list on #3, but I do like the testimonials on the front page. On #2, a telephone number in the upper right corner would help make customers more comfortable with buying. I really like the clean look of #2, whereas #1 looks much to busy for me to actually focus on anything. Hope this helps! Kristin
