I recommend the 4050 Sliverline Plus. It does vacuum and pressure, and comes with a bunch of accessories like brake
bleeding fittings and such.

I made the mistake of getting the 4000 Silverline. Comes with accessories and fittings, but the pump/gauge does not do pressure. Which means I need another gauge setup for measuing boost. 4050 would have done both.
