Combustion Analyzer maintenance cost

Cheeze-Tech

Just looking for a recommendation for a combustion analyzer that won't break the bank to maintain. I was thinking of getting a Testo. I've used a 320 the past with good luck, but have heard its around $500 every time you send it in. I don't have a lot of high paying clients to spread the cost around to. I'm not afraid to spend money to get a decent one but don't want to spend 1/3 of the cost every time I get it calibrated which is supposed to be yearly. Thanks for any suggestions.

Bacharach publishes an NTE for their calibrations - generally around $350 for a Fyrite series, which is fairly reasonable.
Trutech tools will also calibrate some Testo (not 300 or 310) and all Bacharach analyzers for $120, CO sensor replacement is an addtl $150-200 on the Bacharach's, $200-250 for the Testo's, Oxygen sensor on the Testo's is around $130

A manufacturer (Bacharach?) had analyzers that you could replace the calibrated sensors yourself. Who calibrates UEI meter for a reasonable cost? My last calibration, I had to take out a loan from a bank to get er done, gasp. And the meter kit wernt cheap, if you get my drift.
