You can easily and cheaply make your own.  Just buy a hand bicycle pump
from Walmart with a gauge on it.  Be sure it has the adapter needed to blow
up air mattresses.  Now use this adapter with a short piece of hose to the
nipple on your pressure cap.  Pump up the coolant system to 14 psi for the
test.  The cap has a check valve in it that should allow you to pump up the
pressure.  If it won't hold any pressure then replace the cap with a new
"blau" brand one.  Other brands are junk even when new.  Now you have a
pressure tester for probably $10 or less.  Have fun.
