You can certainly do that. Once you try a REVO dream, you will long for a crappy shearwater.
Or you could go the KISS route and it won't be the controller keeping you out of the water, it will be something else.
There are obviously other MCCRs with varying levels of issues.
Basically I am saying every unit will fail, the more you dive it, the more it will happen. They all have strong and weak points. You learn what they are and figure out ways to work around them.
I have a collection of units in my basement and all of them suck on certain days. Most of them are great on most days.
One of them is always a pile of crap, every day. But they are out of business and it doesn't really matter.
