I got the T-Rex earlier in the summer straight from the company for $24 shipped. Though the pic didn't show it, they were the newer style with the grooves. Bolts were right, they have the metal inserts, and they went on in about 3 minutes.
Threw a little blue locktite on there and they haven't budged since. Of course, no one knows until that fateful day when they are need if they actually work or not, but I did my homework and found generally positve reviews.
The left is longer, enough to clear the crankcase in a lowside.
I like 'em. And what I didn't spend on them went towards the Puig Screen and shipping on the Scorpions (which are finally sealed tight and freakin' awesome.)
