Vitol CO-Q10 200 (non)avialability

Somebody in this group (Mr. Cuddly perhaps?) introduced me to Vitol liquid CO-Q10 several months ago. The last time I ordered some it was becoming scarce, and currently I can find only a small number of suppliers that claim to have it in stock -- all at $29.95 or higher.

First, does anyone know of a reasonably priced source? (The first bottle I bought was ~$20 +shipping.)

Second, is there a good alternative?

Thanks,
Mark
