I have had a Manfrotto for the last 10 years and wouldn't dream of using anything else!
Boy, those things are made to last!! Heck, have even stood on it a few times (to photograph over a high wall, it's probably best not to ask) - I'd love to see how long a cheapo plastic one would last with that sort of punishment.
What I REALLY love about it though is that you can bring the legs right up to a 90+% angle to the plate, meaning that you can use it in lots of locations where a normal tripod wouldn't have a chance in hell! I can even hang it up somewhere if I need to. Also, the central column can be removed so that you can lay it flat on the floor/ground, AND you can use the central column to get much elevated (handheld) shots!
In terms of sheer versatility, you need a Manfrotto! (it is modular, so if one bit breaks, you can replace it instead of having to buy a new tripod - STAY AWAY FROM CHEAP CRAP!). You can get multiple quick release plates (in different sizes depending on the camera), so that they live on the camera and you can you quickly put the camera on the tripod instead of having to take it on and off every time.
Oh, and for the record, it is a 190CLB with a 390RC head.
Costwise, it was £100, which might sound a lot, but as I say, those things are build to LAST, so in the long run, it is nothing, and beats having to buy several cheapo ones over the same time period. It works out at £10 a year so far!
