Is it a challenge to change motor mounts?

I think I need to be replacing all my mounts due to their excessive cracking and flaking that is on them. To replace all four, is it a days work or is the removal of the engine required? And does anybody know of some good quality mounts that aren't going to fail in about a few months besides the honda ones that tend to go?

stock motor? nope nothing other than OEM that I know of. energy suspension makes some inserts but ES only makes them for the left and right mounts and they're just designed to stiffen them.

yep, all stock d15b1 miracle worker! I really don't want inserts cause I do see some stress on one of the mounts and replacing the whole thing on all four would be wise. and there has to be something other than oem mounts.
