I get mine from signwarehouse.com because they’re located in Sherman TX, so shipping is quick.
(and only ten bucks, which isn’t bad considering the weight and bulk of some rolls)
I also like the clear stuff and dislike the grid pattern. I haven’t tried a lot of brands, but I like R-Tape Clear Choice and they have a good reputation it seems.

I haven’t shopped around on this stuff in a while though, so there may be a better vendor. I bought a roll of 10.5"x100 yard more than a year ago and I’ve still got a decent amount left.
EDIT: looks like uscutter is about ten bucks cheaper, but they’re in Seattle.
Choosing high tack vs. low tack kind of depends on the vinyl it’s being applied to and the subtrate it’s going on. Here’s an article to help decide. Like all things, YMMV
