Until recently, I thought that the only laser power meter available for testing my 80W CO2 was the synrad power wizard 250. They're pretty expensive, so I was looking around for alternatives. After some thread searches, I see that there are a few choices in both digital and analog metering. A few that I have seen are made by Macken (digital DM5 and P-series analog) and by Mahoney (analog).

For those who have used either (or both) I was wondering if you had some feedback on the accuracy and useability of these meters.
What reasons would you prefer a digital over an analog?
How does the synrad PW 250 compare to the macken digitals?
At Macken, they say both their analog and digital models are accurate within +/- 5%. I'm not sure about the Synrad. Have you found this to be true?
If I understand correctly, the analog requires a longer pulse to get accurate readings, and doesn't lock in on the highest read. One has to watch it and take note of highest reading.

Having used neither type, and wanting to purchase one in the near future, does anybody have a preference, and why?

Thanks!
