I have a Ravelle Deluxe, which is one of the non-Sustainer models. It comes with Seymour Duncan Jazz and JB pickups stock. Of my "top 5" always-dependable "first tier" guitars, it is the only non-US built (others are two LP's, a '52 RI Tele, and a Hamer Special). It could easily be a person's number one (I intentionally rotate my guitars at gigs). Build, fit, and finish are top notch.
Can't give you any info on the Sustainer. I'd never use one, which is why I got a Ravelle without it.
Reportedly, the Chinese-made ones are actually better than the MIK (production started in China, was switched to Korea for a couple years, then back to China) ones. Mine is one from the first batch of MIC Ravelles. I haven't played any other ones so I don't know how true that belief is, but it seems accepted over at the Fernandes boards.
I got mine for $400 used but minty, on consignment in a local mom&pop.
