[QUOTE=tvphotog;8382356]Slik and Bogen Manfrotto make excellent products in this price range. I don't know if I'd purchase a tripod at anything but Amazon, B&H or Adorama, and if you stay with these two makers, you'll be fine.
Here's a review of the one you mention. http://www0.epinions.com/content_190024093316
I would throw in a couple more bucks, and get one of the less expensive Manfrottos at B&H. Call them and speak to a salesperson about what you want and how much you have to spend. They're all moonlighting photographers and won't lead you wrong.
This is the one many here recommend: Manfrotto 055XPro and 488RC2 head.[/quote]
I use that combination. It's an excellent, versatile tripod and the head performs well on it. Keep in mind that you have a 400D now, but what about next year. Maybe a heavier body and lens?
