My favorite cash-in was easily Punk's on Jeff. At that time in wrestling, Jeff was one of my least favorite wrestlers in the company and Punk was one of my favorites (probably second, with Shawn beating him barely) so it's pretty freakin' obvious why I loved that one. Rob Van Dam's is a definite second though. Was a big Van Dam fan, and I'm still a relatively big fan (a benefit of not watching TNA I guess [also, it's hard not to be a big fan when he's involved in my second favorite match of all-time]), but besides that the fact that it's one of the only announced cash-in's help. And besides that the match was really great too.
