I sell and install the AstroFlex unit out of Canada. It's one of the best starters that I've seen in the industry. Check them out here http://www.astroflex.com/english/intro.html

I have the model 1105 installed on my VX. It boasts about a 1/4 mile range and holds pretty true to form. I started my VX from my seats in Gillette Stadium the other night after watching the Patriots get spanked by the Jets.
