Perhaps the following rumor will affect your decision?
I have heard there will be a new DC12000 (and DC6000) released soon. Originally it was scheduled for release in late march, however it has been delayed until late April. The new pump is supposed to remedy both the leaking o-ring issues as well as the thread mismatch issue. The first batch in late April (if they don't have further delays) will have a standard controller available similar to the existing one; however there will be a new controller/interface released a few months later that will have Apex Aquacontroller (and possibly other controller) bi-directional communications via USB (NOT RJ45). This means you will be able to control the speed of the pump via aftermarket hardware without the need for a VDM module, but even better you will be able to view pump RPM, and possibly temp and other diagnostics via your AquaController (and other?) interface and thus setup alarms to alert you if there are issues. The new WaveLine controller/interface will be available as a separate purchase and will be readily swapped out on the DC12000 but not on earlier generation pumps (ie you won't be able to make your DC10000 controllable via an Apex or other external unit).
There is talk of a 'relatively easy' hack on the DC10000 that will make it 0-10v controllable, but you can do your own research on that
.
To my knowledge this information has not been officially released by Waveline so treat it as rumor. Also, I don't sell, represent or own any of these pumps, I am just very interested in what they are doing.
I plan on running a pair of them as return pumps, one on each side of my tank. I will run them anti-sync with around a 30 second ramp from 20-80% and back down to 20%, the idea being to create surge while maintaining redundant return pumps and eliminate or reduce the need for circ pumps. One note of cuation though, they have a 30 second ramp time built in to the on board controller for slow startup, so you can't run them to generate a wave as they will auto ramp up slowly on their own.
As an aside, you can look up Diablo DC pumps. The design seems to be identical and I suspect the flow graphs to be the same as well.
