Don't buy from HigherFI.com

PayPal handled my past claims quite differently then your experience.  They did not transfer me to e-bay, they processed the claim and I was refunded my purchase amount within a couple / few days. They just asked me to return ship the item.  It may be because you filed a claim through e-bay (Prior to PayPal) and it was closed by E-bay (assuming not in your favor) is why PP forwarded the claim back to E-bay.
After E-bay refunded you $40.00 for your RMA shipping, you don't really say, if they are going to provide further solution, instead you state "Its wait and see now".
I am in agreement with sevs, you should file a claim with your credit card company, if you have not already. Usually it takes a phone call and your account is credited the refund. At least that has been my experience.

Honestly, I don't understand how this Moon character has such good feedback and even a great referal by none other than Bill Leebens - Director of Marketing/Audiogon,

Maybe like contractors, they are as good as their last job?  

@OP,
Ebay has a concierge service that they offered me. I have to say it really is pretty good. I wonder if you can opt into it?
FWIW, the seller has to refund you should the item not work as described, even if they say it is 'as-is'.

I'm gonna guess that you closed the claim when you got your RMA #. Likely at Moon's request. Would suggest keeping claims open until return/ refund process is concluded.

2 Cents worth:

I had a well executed magnetic platform with a VPI scout and  Dynavector Ta Kura (sp?) Rue cart. While it did make for interesting conversation with house guests, the magnetic field killed the sound of this low output moving coil.  So, I put a big walnut amp stand on spikes on top to move the turntable about 5" higher. This made all the difference in sound. I never found any sonic benefit that I could identify from the whole magnetic platform concept. The weight of the turntable alone caused a rather stiff compression of the magnetic field that transmitted the floor and sonic vibrations from what I observed. And if you think about it, why would a powerfully linked magnetic field somehow dissolve vibration energy. Aren't most speakers working a electrically energized field coil producing sound by interaction with a strong magnetic field. I suggest you save your money for something more beneficial, like a tube-preamp or better cables.
