Here are a couple economical choices. I use the FB620 for a G&L Tribute JB-2 I have, and it's worked well. The other link I posted is for a short-scale bass, but given the lack of a head on the NS basses, it might actually be a better fit. Other than that, I know nothing about it. It appears NS Design doesn't offer their gig bag for sale, though if you're interested, you might call them. They're contact info is available at thinkns.com.
