Cheapest Place For Polyurethane Tranny Mount??

I found this one http://www.ls1speed.com/catagory.cfm?catagory=trans from LS1 Speed, but I'm not sure if it's Polyurethane? It says it's made by Energy, but that it's made of "HyperFlex". What's the difference and can I find a cheaper one made of Polyurethane? Thanks.

I'm using a Prothane mount:

It's only $19.95 and it works fine. Their engine mounts are nice too.

I was just going to ask the other guys that have them... didn't you find them too stiff?

I did my entire car in poly mounts and went back to rubber tranny mounts because it was harsh and noisy.

Actually, I noticed no difference in vibration going from my stock mount to a 1LE and then to this poly mount. And from my observations here it seems most of the people that complain of vibration with it are the A4 guys, a lot fewer M6 cars seem to have a problem with it.

I broke a few factory tranny mounts then got a hard vulcanized rubber one from SLP and haven't had any problems since. Vibrationwise its quiet and smooth as stock.
