LiveWire Speed Minder vs Trafcam

I'm still considering various options for a speed camera alert system, with the possibility of navigation as well being a bonus.

Assuming I go for a PDA based system, what's the best camera alert system?

I've seen mixed reviews of Trafcam, but it appears to be generally OK. The LiveWire product seems to be a bit mysterious though, and a Google search turns up barely a mention although it has a much more professional look to it.

Trafcam's database seems to be maintained by volunteers and public spirited users, and I've no idea how the LiveWire database is maintained.

Do either of these offer any real benefit compared to the Pocket GPS World camera database (assuming a Pocket Windows PDA with TomTom Navigator)?

Thanks!

The benefit would be continued support from the developers since your paying for a product. With the PocketGPS database it's not always going to be their main concern (not that they neglect the speed camera database) but in my opinion the cheap option wins it for me.
