That was going to be my next question actually, Andy... what valve is best to get. Theres obviously differences in each brand/type. I looked at the compbrake ones cos someone was selling one on here the other day, but i got beaten to it (again, typical lol), but then wilwood is wilwood innit.... Are they all similar and just do the job in hand, or are there some that are really worth avoiding?

None seem to come with the t-piece bit either... but i guess thats readily available too?
