Its always worth remembering the tripod has to be able to take the weight of the camera and lens you use. When I moved from a Canon 350D to a Canon 7D (via the 40D) I found the Manfrotto kit I owned couldn't cope with the extra weight. The junior ball head on the 190xprob was not designed to take that weight
www.manfrotto.co.uk have a superb 'configerator' that lets you build a system around your needs. It shows you whether your choice of legs and head are balanced and the final outcome of what you want to use it for will give you the options to look for
Theres an old saying "You get what you pay for" and thats certainly true with Tripods - better to wait and get one that is suitable than buy a cheapo one that can't cope with the conditions you are asking of it.
