I Just figured I would share this info with the forum, because I was unable to find out the answer online. Hopefully this will be useful to someone in the future.
Anyway, I just bought the SKB roller flight case for less than $120 (with coupons) and the Epi Jack Casady fits in it (with the gig bag)! Granted it's a super tight fit (really tight), but it's stable and it definitely won't be moving around in there. So, anyone in need of a dirt cheap flight case for the Jack, give it a shot. You could always return it if you're not happy... Amazon.com: SKB ATA Rated, Electric Bass Safe with Wheels (Hard Clamshell Design for Use with GigBag): Musical Instruments
