GPS questions?

[Mr.BubblesVRCCDS0008]

 I'm fixing to burn up some safety points at work. There are three GPS to choose from, from least to highest they are nextar 3.5, megellean 3.5 one touch roadmate and megellan 4.7 one touch roadmate. Anybody have any dealings with any of these. Nextar is 40,000 points megellan 3.5  70,000 and megeallan 4.7 roadmate 100,000  so is there that much difference in quality and features. TIA

as in anything, you get what you don't pay for....

Not familiar with any of those models.  We use Zumo 500 and TomTom 730 on our bikes.

Narrowing it down to megellan 1470 and Garmin 265WT about the same in points but I think I'll like the Garmin better. Now goota figure out which mount to use and where.
