My in-laws have one for a weekend place. After they had it stained and sealed about 7 years ago, I don't think they'd done anything else in terms of maintenance. Seems to be pretty efficient, but then again, they only use it occasionally.

The biggest problem they ran into is that the only company that would insure it was State Farm.

thanks beckiebob.....I just got off the phone with my insurance agent (State Farm) & he said they will insure it at a rate just slightly higher than conventional construction as long as it was built from a kit and we can identify the original mfg...just in case we ever need replacement logs. I had read that insurance rates can be as much as three times higher and require a $5000 deductible...but I guess that's not the case.
