I'm in a similar position, I reckon I might go for the Wiggle one.. Seems to have a few more specialised tools you can't just pick up cheap at a DIY store (adjustable wrench/allen keys/screwdrivers etc)

My reason for getting one is, I've come to the point of requiring those special tools, i.e. BB Remover, chain whip etc.

That's just my oppinion though!
