I've got a sec@6 Daytona rep that has been running strong for the last 5 yrs. I just had it serviced for the first time by Zigmeister, and he says it's a keeper. I think it's more luck of the draw. I've chatted with a few others on the various forums who all have had no problems with theirs.
In fact, I'm wearing it right now!
If you really love it, buy one and send it to Zigmeister for a proper tune-up and inspection. Get it lumed while it's there too!
Just be aware that a lot of them have failed...
