I've had good luck with the IC-Gel, before that I was using epoxy and that was a PITA. I've never tried other superglue products and since the IC-Gel is cheap I see no reason to.
the dollar tree stuff is great if you are only doing one or two frags. the big BSI tubes are the best if you frag alot. I got through one of those tubes every two weeks...so it works out for me
