Compression Tester and/or a Leakdown Tester

[BrightBlue00GT]

I want to add a Compression Tester and/or a Leakdown Tester to my toolbox. Anybody have a good on-line source I can purchase at? What brand should I look for? There are quite a few out there.

I ended up buying my leakdown from Summit for like $65, works very well. My compression tester came from Sears for around $30, also works very well.

got my compression tester from e-bay new for 30 bucks, as well.

I have a different question. It must be simple because no one else seems to question it. Anyway, all of the compression testers I see have fittings that are 12mm or 14mm. Do these fit a 66 mustang w/ 289. Is there a better make or model, considering I'd just use this every few years?
