Remember that any mods/repairs whatsoever will void the warranty. Even stuff not even remotely related to the broken on/off switch. I know it did not take me very long to void my warranty. How much do you use the unit? I use mine a lot. If you return it, you will have to wait a while to get it back. A new on/off switch from gigdigit.com costs $3.95. If you are not a total klutz, you could be up and running in a couple days by fixing it yourself. If worst comes to worst and you really mess it up, you can buy a new one for $179 and have lots of spare parts.
