i have
THIS ONE for my PDA phone. works quite well.
they also make
"THIS ONE",
which i would really like for my gps but they don't make a bracket for it yet.
i have been real happy with the one for my phone if anyone is interested. i have the one that hardwires the power and the whole thing is very sturdy!
PS, i don't know what is going on w/ the url posting, never had a problem before.
