I got a cheap $80 one and it's been running pretty much constantly for about four months now. I have no experience with nice ones. Mine came with a pound of different rocks to try, too. Mainly, you want to have similar size and hardness rocks together, or else the big, dense ones scratch up your subby weak ones.
It's white noise and louder in the first stages than later on as the rocks get smoother. Sounds like a babbling brook, but I wouldn't want it in my bedroom. Should be fine in a garage, but maybe put it on a grippy mat so it doesn't rock itself off a table. I keep mine sandwiched between blocks of wood.
I haven't looked at what kind of power it's drawing but haven't noticed a difference in the electric bill either. It's just a motor that turns so I doubt it takes a lot to run.
Hey, thanks for your reply! I started looking at Amazon and the many reviews. Hopefully I can choose a decent one. That's also reassuring that I can pursue a hobby that doesn't raise the bills LOL aside from the fun of going out and finding the rocks of course.
No problem!
