Any racks that use coasters/ wheels ?

+2 on Herbie’s gliders.

Clearly racks are not designed for usability by most people. Once you put them someplace they pretty much have to stay there. Mobility is lost.

Why don't rack manufacturers do a better job here.
 

I wanna stack two Mono blocks but there is no rack that is sold with coasters. The rack is too small, etc. A wonderful market opportunity that no one takes an interest in.

To the OP, why start a post if you've already made up your mind and are not interested in other peoples' experience and opinions?  Just curious.

+ 3 on Herbie gliders. I am using the ones which accept spike points.

@emergingsoul  No opinion about coasters, but I have read monoblocks are best utilized close to each speaker. Supposed to improve the sound quality using short speaker cables and long interconnects.
