Nothing crazy about that-- I wish more people would take this approach. A US Duo with a tuned (or new) laser and a capacitor replacement will outlive any R or RX.
Sounds like the new laser wasn't calibrated (or at least, wasn't calibrated correctly) on install. If you can get the laser tuned correctly this Duo should outlive any R or RX you might pick up. You're already 95% of the way there!
Plus the US duo is sooooo sexy looking!
I had some rough spots with my Duo early on, but now that its got a new laser and some new sound caps, its perfectly reliable each and every time I use it.
DMD, if you want, send your duos to either me or chop5, one of us will get them running perfectly!
