I have the ES motor mount inserts, not yet installed on my 93 se-r, if you want to check them out.
I bought them from: http://www.mossyperformance.com
They were the same price as Courtesy.
My brother had the ES inserts installed in his '91 se-r about a week ago. He said they made a huge difference - due to a worn out stock firewall mount.
For the money, I say go with the ES inserts. They're like $34, got mine the cheapest I'd seen them at www.ptuning.com but shop around. Although more vibration is transfered to the rest of the car with the inserts in, the engine feels solidly mounted and there is really no play, so all that torque is going where you want it to, to the drivetrain. I wouldn't spend the money on the PR mounts unless I was building a full out drag car or was going to be putting down some crazy ass HP numbers. Even then I might consider chaining the engine instead, it'd be cheaper and even more solid.
