supercharger installation dealer or aftermarket (Phoenix area)

[jebia]

Called the local dealer, they want $10k for a vortech installation (no affect on warrenty).

Called AZmarine and they want $5.7k for a magnasun (uses the eton supercharger) intercooled kit. This price includes the magnasun warranty supercharger warrenty as well as a engine extended warrenty that is supposed to help up to $5k towards any engine problems (factory engine warrenty will be voided with this kit).

I'm inclined to go with the magnasun. Any recomendations or experience with either incall?

thanks in advance.
