Mounts again advice before purchase please

[a4gom]

I am about to purchase the TomTom Bluetooth Navigator III with iPAQ 4150 bundle with a 256mb card, which mount should I buy for my car?
It appears I have 3 options but I'm not 100%
1/ Seidio Amplified Mount £39
2/ TomTom Car Kit £39
3/ InterPDA Mount and 12v charger for PDA total £39

A second question is how is the bluetooth gps reciever powered? rechargeable batteries? can this be charged in car?

TomTom Car kit @ £39.
The receiver has its own built in rechargeable battery and will come with a lead that connects to the side of the TomTom car kit for charging.
