I just bought the TRV60 (European model of the TRV70 in the US) about 1,5 month ago. Been jumping an old Sony HI8 camera for quite some time before switching.
The TRV60 is freely mounted on top of a Bonehead Optik helmet. After about 40 jumps with the camera I must say that I'm more than satisfied. Works like a dream and gives excellent result.
For me it was worth the extra. One excellent feature is the 16:9 format. I'm the only one at the DZ that can record in 16:9 and it has so far given a couple of extra jumps from people who prefer 16:9 over 4:3.
