If your on a budget go buy an ACS claw there usually prety reliable + cheap if they go boom. I'd suggest buying an eno or tryall, their both expenisve but there uber good quality, especially the eno because you can replace all the components if you manage to kill anything on it the tryall just has awesome engagements 108(which is more engagements than everything else on the market), meaning you get an engagement every 3 degrees although a few people have had problems with them skipping like a bitch. If you've not got the budget go for a tensile, there awesome value + such.
