Re: JBS: DC- regulator blown second time; what's the cause?

Hi Bluechip,

thanks a lot for your clear and honest words. I think you're right! I'm
actually looking for a replacement unit. But all I found on Ebay was - for
my sake- too expencive. Even broken units cost (without a HD) cost about 30€
(40$) and a simple JBR6 where I even have to replace the HD costs 90€ (120$)
which I find too much since i can get a brandnew Gmini120 for 180€ (240$).

So I think I'll go for a Gmini and wait until Rockbox will be available for
the Gmini (perhaps I'll try to help the guys a little bit if possible)

Cheers,


Markus
