Recommendations for simple small Variable speed ECM Pump?

The Steam Whisperer

Need a small ECM pump for my home system....around 5.5 gpm @ 2.5 ft. hd.. probably just a simple variable speed pump should work that I can just dial in the flow. A long time ago I beta tested the B&G variable speed ECM pump and I remember running about 9 watts for the pump in the system for my old house that was very similar in needs as my current system.
I plan on making this my test bed for a direct comparison of a steam system vs hot water system to compare fuel and electricity usage using an identical system, building and boiler. The piping is set up for use as a two pipe steam system or two pipe hot water system. I will probably use a Peerless 63-03L boiler, unless I can find a good steamer at around 60,000 btu/hr input.

Basic circ, or lots of bells ands whistles? I saw the new Grundfos UPSe 15-58 and the higher feature Alpha 15-58 a week ago, pretty impressive, new functions.
The Alpha gets you touch screen Bluetooth, etc if that interests you?

Should be able to find You Tube info on both.
Do you know the folks at Lyall -Thresher? Maybe they could hook you up?

Just keeping it simple.

Pick a color, all the pump brands have basic, small ECM in the $200 range. I like all the speed settings on the Vario, it tends to be more $$

I have a few Alpha1 15-55 circs. The one on my boiler loop is set to "I" and ramps up to 43 watts unless I throttle a valve. Same circ on radiant set to "II" only draws 26 watts due to more restriction. 

Boiler loop is 1.25" and radiant (5 loops@ 300') is 1/2 PEX.

I have an Alpha 2 that I run at constant velocity level I on a converted gravity system with 2” main lines. Pulls 8 watts moving 4GPM cold and 7-8GPM at operating temp.
