There are lots out there, I am asking opinions from people who own them

I usually stick with Venmar/ Vanee HRV but I want to try the german product below:

Lunos e² - One pair with one controller : Four Seven Five, High Performance Building Supply

All the super high efficiency stuff comes from Europe from my research. Sorry, I don't have one to give actual feedback.
