Origin DC Motor in LP12: Marketing or reality?

I have asked this before and gotten NO (zero, nada, zilch, bupkis, null...) response. From what I can tell, there is 10 times (100x?) the amount of promotional material as there is personal experience of this upgrade on the internet. I am starting to wonder if they have ever sold any.

My TT is a Linn LP12, with Linn Basik Plus arm and Clearaudio Virtuoso Wood MkII cartridge, and it is fitted with the Valhalla board. I have a great isolation stand that gives me incredibly musical and natural sound and I love this in my system. I do not want to screw up the sound, but I'm willing to try to improve it without spending big bucks. I can afford about $400-600 for a large upgrade at a time, once or twice a year.

Everyone I know who has added a motor drive (Lingo, Walker, Clearaudio, VPI) reports fantastic results, and I have heard it myself on many of those systems.

I have considered, on and off, trying to upgrade with the Origin Live DC Motor Drive, but I can only find about 2-3 professional reviews, and no individual (amateur) critiques, just comments from people who have read about but haven't actually installed one.

Have any of you actually tried this upgrade? Would I get a great improvement over the Valhalla board? How does it compare to a Lingo? What are the pros and the cons?

p.s. Does anyone else notice that there are certain products that are very heavily promoted in this and other sites (classified and dealer), but rarely see comments about someone who bought the product?
