Are the blackberries that have GPS built in just as good as the bluetooth GPS pucks. What chipset does RIM use and how is the power consumption. I am debating on upgrading to 8310 when it comes out or should I just buy a puck.

If I recall correctly, the gps chip is a Sirf III, which is the same type used in the larger units (TomTom, Garmin, etc) and will lock on fairly quickly (always a subjective term).
I have the 8310 and yes the GPS uses a fair amount of power, but it's not been an issue really thus far as the battery life on the 8310 is quite impressive. I'm using the standard Curve battery, which is 1000 mAh. Just as a matter of course I ordered a 1300 mAh battery from Seidio before I even got the phone, because I've needed an extended battery on previous phones. Thus far, I haven't received the extended battery, but I haven't needed it either.
I know they make a larger extended battery that's 2600 mAh and comes with a larger cover to accomodate the physically bigger battery. I'm not sure if either of these things sway you at all, but personally, I like having the integrated GPS. If you don't mind carrying a puck around, that sounds like a workable solution as well.
