Hmmm look at that - only $44.95. Save your money.

Check out:

http://www.racerpartswholesale.com/

on the left, click on Longacre then select leakdown tester.

That's more like it!

There are other sources, I'm sure I've seen a reasonably priced unit in a
local AutoZone (like under $75). Major parts suppliers should carry them
too.

A single guage will be prine to errors, as you have to use the same meter
to see initial line pressure and then the cylinder pressure... with a dual
guage, you see both at the same time, and because if the volume of air
needed to "fill" the hose and combustion chamber, you can adjust the line
input for the initial line pressure that you desire...

Once you use one or see one in use, it'll all make sense.

I'd stay away from cheap guages...
