I've had really good luck with aftermarket mounts, though I haven't ever bought the ones from any parts house. I am rather found of the urethane ones. They claim to last much longer, and some are redesigned to hold better in the event that they do fail. The downside is that you will feel the engine more. Stiffer material so the vibrations transfer more readily. I personally don't mind the change in feel.
I can't see what engine you are running, but Polka just did his a month or so ago on his 5.9L with some really nice looking engine mounts, and he raved about them. You might check that out.
My engine is a 5.2. I dont think I'd like more vibrations from my car. I will give stock mounts a chance first.
