Other What is a good compression tester

[icecoled007]

Can anyone recommend a good compression tester? Better yet reccomend one from Advance Auto Parts: http://shop.advanceautoparts.com/we...=&selectedPartNumber=&qty=1&ship2HomeClicked=

Because I have a $40 off $100 coupon code.

My $12 one from harbor freight worked good.... once now it keep giving low readings (I hope its not my ski)

I think mine is just the cheap Sunpro. Has worked great for a lot of years and has tested accurate against some big dollar testers.
