Which Puck?

Alright, I've been reading how VZW bans GPS except for VZNavigator, which I don't want to spend $10/mo for. I deliver pizzas, so a GPS is a must have for me; currently using an out-dated Magellan POS, and was thinking of upgrading. Figured, why not just get a BT GPS reciever and use it with my Curve? First off, I can do this right (I've heard most say yes, but a few said no)? Secondly, what receiver would you guys recommend? I want something small, that has good accuracy and update, and preferably under $60. I was looking at the i.Trek M5+ for $40, and it looks like a decent receiver, but I haven't shopped for them in a few years.....

When I had an 8100, I got the TeleNav GPS off of ebay for about $30. Worked beautifully for me. It sat on a velcro strip on my dash. Recharges via the same mini-usb your BB does.

Alright, I've read alot of good reviews about the i.treck, and it looks good, so I think I'll go with that. I already downloaded a few GPS programs, but ran into an issue alot of 8330 users do; the speech gets cut-off. Has anyone found a way to fix this yet?
