Hi milacqua,
I should have mentioned as well that there may be some good options that are close to you and if you let me know the city or zip where you live I’d be happy to link you to some of the better options or possibilities in your area I’m aware of.
Just in case … Dallas is listed in post #4 here and Austin and San Antonio are listed in post #2 here and Houston is in post #2 here which may give you places to either do some testing or in some cases the value may justify a purchase as well.
In most cases the DC motors are quieter but not as strong as the AC motors.
The weight ratings for Ergomotion are here (click the question about weight limits) and weight ratings for Reverie are here. When I questioned Reverie about their weight limits … they they told me the information is not correct and would honor a higher weight limit. They also sent me an “official” email with a higher weight limit which you can see in post #3 here although that was over a year and a half ago and they don’t seem to have changed their literature since then so you may want to check with them.
