So the website of http://www.billyrhythm.com/drums/ghost/ says to contact him with any additional information, but there's no contact link or other info.

An ideas? I've got a couple of 'Ghost' questions....

e.g. -- do they need ANY maintenance? Id there a way, or a need, to squirt a little lubricant into the spring coil 'chamber'?

I'm also going to pm Mikey777 as it sounds like he has mounds of experience with these eccentric machines.
