Great poll, should be very interesting to see the results.
I voted "I own a USA Duo and have never had to repair it", however I must admit that I am scared that one day I will need to repair it.
Yep... i am with you there 100% my friend in both accounts.... shes still going strong but i have to admit also i have been using my TG16 Cd unit with the 3.0 card more these days to keep the freak'n gremlins out of my sweat ass duo :-"
I would keep using the Duo over the TGCD if I were you:
1) AC adapters and lens are easier to find for a Duo than the TGCD.
2) The TGCD has a little plastic gear that wears out and loses teeth. Nothing short of buying a second unit for parts will fix that.
3) I've seen more advice on the internet for repairing Duos than TGCDs.
You're going to have to do some work on either one sooner or later. Duo's load slightly faster so you might as well use that for CDs. Keep your TG16 with just the CD interface hooked up for Turbochips - less wear and tear on your Duo's hucard port and all of your tiny Turbochip save files will stay in one place instead of cluttering up your Tennokoe banks.
