They appeare to have a lot of potential.

I have.
I purchased a lot from Tam Valley (Octopus 3)...enough for 36 turnouts. Bought the servos and servo wire from eBay.
The good is the price. The bad is calibrating the servos and electrical noise......I performed a decoder install into a brass steam loco and when I went to test it on the layout, and as the loco approached the turnout, the servo started to erractly switch the points over and over again. I was using toggles to operate the octopi. Tam valley mentioned snubbers on every toggle (wasn't I the instructions), but at that point the damage was done and I couldn't let something exist on my layout that may cause a customers loco to fall off the rails or worse. I made sure the wiring was away from bus lines...etc.

I'm using Tam Valley Quad boards and (mostly) SG-90 servos (less than $3 each direct from China). After 2 years, all is well, except for the lone non-SG-90 servo on the layout, which has become noisy. I'll have to swap it out for a SG-90.
I have no problems with interference in the servo system, but then I do not run any brass locos, either. Calibration was not a problem for me.

The Tam Valley quad boards have a servo-off feature. Just ring up the offending servo and add that feature. It just means that after the servo does its sweep, the board will remove power from it after a few seconds.
