Aside from those made in China, which everybody says are junk, is there a better brand to get?

I once drove a 300d, W124, that was totally, totally, completely motionless at idle. I'm sure there were several factors attributing to that, but motor mounts would surely be an important part of the mix.

Someone said to get fluid filled motor mounts vs. all rubber. I don't know.

I've heard a few different brand names; Phoenix, Corteco, and Hamburg Technic. Any real difference in these?

Thanks,

.... updated now that the job is done..... I went with the Corteco. I thought no sense in saving $40 or so on a set, and not enjoy the car as vibration free as possible. The Corteco's are the OEM replacements.
