JC Whitney Fuel Pressure Gauge

[Steve Sherman <steves@cyrix.com>]

Someone poseted a while back that JC Whitney (of all places) has a fuel
pressure gauge with the right fittings for CIS system at a reasonable
price.

I checked and indeed they have one for about $50. Which is about 1/8th
the cost of the official VW tester.

My question to any who might have bought this from JC, is what is the
quality like?  Is it likely to be of use in a real diagnostic
situation?  Will it last more than one or two uses?

TIA
