Compression Tester Recommendation?

[FWBennett]

OK I'm in the market for a compression tester for my 84 6.2 Suburban (my old gasoline one isn't gonna cut the Diesel Compression)- what are you using? Where'd you buy it - would you buy it again or go another direction?
- Thanks!

I have a Matco CT155 tester, it comes with 5 or 6 adapters for automotive applications. Cost was around $150, I think - it's been a while since I bought it.

I've been eyeing this one after I found him through ebay:

with the adapter for our engines it comes to just under $50, but I haven't ordered it so can't comment on quality.
