I think the Serac will be a fantastic table for around $2200 with no arm and around $300 more with the Rega. I believe Thom is working out a deal to possibly bundle another higher quality arm as an option for a little more.
As far as costs go, don't forget that there is an additional $400 charge for shipping and a custom case - so that makes it a little more expensive (but still a bargain)
I couldn't wait until the release, and bit the bullet cost wise and went for a Raven One. If the Serac were available, I'd already own one. Plus Thom is the kind of person you want to do business with, on every level.
