I'd take it to a Mazda dealership. Some dealerships are good, and some are bad.. so ask in your local forum, to find out the good dealerships in your area.
Rotary compression testers cost about ~$800. Or you can use an ordinary compression tester along with a video camera, to record the 3 peak readings and view them on playback. Remember to use WOT when doing a comp check.

They have one on Ebay, about $400, not bad.
Considering how much hassle and money is lost on bad engines, $400 is not that bad of an investment.
Found the auction, and no, it isn't mine.

"And The Almighty Factory Service Manual (1985)spoketh, and it revealed unto me that the compression shall be 85 psi, and that the difference between chambers shall not exceed 21 psi. Amen"
Now I need some divine intervention on the ignition switch, as my $40 compression tester has been sitting in the engine compartment for a week. I plan to have my lovely assistant turn the key whilst I watch the needle bounce.
