The ones I have seen usually have two or three Lamb two stage motors (like the 116336 or the 119414) in parallel, giving them similar performance to an MD B/E2 or E3 (or the Filtex equivalent like TSP700L or TM285). They have plenty of room under the dome to play with different motor and control configurations, so you're not limited to the coin-op timer mechanism or motors they come with.
I thought about acquiring one years ago. My plan was to mount it outside (as they normally are installed) next to the trash cans and pipe it through the wall into the house, connected to piping and inlets. Outside exhaust, outside noise, outside debris disposal! But...neighbors and HOAs and so on. Glad that plan never came to fruition.
However, given this opportunity to live vicariously through you, I offer my wholehearted encouragement!
