CF or Bluetooth GPS receiver

[nigelbb]

I have a Dell Axim x51v & want to get a GPS receiver for it. I see that I can either get a Bluetooth unit like this http://cgi.ebay.co.uk/32-CHANNEL-BLU...QQcmdZViewItem or a Compact Flash one like this http://cgi.ebay.co.uk/CF-GPS-RECEIVE...QQcmdZViewItem

What are the pros & cons of Bluetooth versus CF?

usuin a cf on means you cannot then use the slot for a mem card. also it may drain the pda quicker. a bt unit can be used with any other device so would be easier to sell on in the future
