Hello,
The AirTabs are $200 (for a set of 80!) or $2.50 each, and the Vortekz are $20 (for a set of 10). I'm thinking of 2 sets of the Vortekz...10 for the roof, and 5 on each side, or maybe 3 sets...here's what they look like:
Now that I think about it, the AirTabs are $25/10 and they are larger, so...I dunno yet.
