I'm still running first release first gen apex (now called classic) and I really trust the gear. I've had it for more than a decade. And the display is the only thing that's failed me.
I've been looking to upgrade and of course, if you look for horror stories you will find them. I keep hearing about eb832 failures due to the bum 12v power converter module. The idea of a bad eb832 does concern me. My control strategy/philosophy has always been centered on isolating risk. I love the idea of a smart pump that integrates with a controller, but I love the reliability of an ac pump directly plugged into the wall even more. I like controlling equipment that has it's own onboard controller and using one or the other as a failsafe.
I know it's all just rumors and conjecture at this point, but it would be exciting for a new version to be released. It's a bit odd to me to see so many people take the "what could they possibly do better" position on technology development. I ,for one, am excited to see what they come up with that is better.
