I ended up with the iGuidance and OnCourse SiRF Star III BT from buygpsnow.com. Have had for about 2 months and has more than met my needs.
:approve: First off - Bluetooth rocks! No cables, cords, tiedowns, tangles, plug in problems. It does not use the battery in the Dell like a CF connection does.
:approve: The SS3 is very good. I've used it from cities to the canyons of Utah and always had a signal. Cold start has been less than 60 seconds and warm is 10-15.
:approve: IGuidance software has exceeded my expectations. I got it for basic dependable maps and directions. I've seen Tom-Tom and it's good too. Frankly, I never use 3D view.

Arkon vent mount......jury's still out. It works on my 91 Honda but not on any of my other cars or rental cars I've had in the past 6 months. Different clips?
:approve: buygpsnow experience was very good. I emailed questions and got intelligent responses befor emaking a choice. Asked customer service a question after the sale and got a very good response. Very good = intelligent, didn't make me feel like I was bothering them, fast and accurate. The bundle price was very reasonable.
Have fun!
