In the size you are looking for, a used DK Models Type VII is about all that's available. Notice I said "used"; there was some talk of Dan Kachur spinning up production on more 1/48 Type VIIs, but I don't know if this ever happened or not.
In a smaller scale, you could always buy the 1/72 scale Amati Models Type VIIB and cast a glass hull from the one provided in the kit...lots of scratchbuilding needed for this project. There's also promise of the plastic model from Revell later this year....
You have far more to pcik from when you move up to 1/32, but that's beyond the size you are looking at.
what were once vices are now habits
