Like it says -- can anyone recommend a good GPS module? My requirements:

1. Must plug into my Sony Vaio laptop -- this is going to require USB, firewire (4-pin), PCMCIA. No serial.
2. Must work with decent mapping/route-finding software -- only the UK required at the moment, but Europe and the US in future, maybe.
3. It'd be cool if it had a storage facility, so I could stuff it in my backpack, and retrieve "telemetry" later -- where I've been, how fast I was going, etc., etc.
4. It must be reasonably cheap.

The idea occurred to me while snowboarding last week. Fortunately, I don't have to map the resort I was at -- someone already has.
