Agree with the whole "get one as good as you can afford" thang...
Tripods don't revolutionise overnight, so if you get a decent one and look after it, it'll last you... Well, forever.
The Manfrotto Digi range are very good, my cousin uses one.
However, I would recommend spending a little more and getting a 190 (or variant thereof, 190 pro etc..) and a decent head.
I use a 190 Pro and 460MG head
