Hi DGB,
This would probably be better if posted to the "ships" category of the forum but I'll tell you what I found out. I've seen this kit priced anywhere from $30 to $60. It started out as a Renwal kit as you've noted but it's been re-released by Revell. From what I've read, the interior is not accurate and it seems like some builders of this kit tend to paint over some of the clear parts but they leave it clear over the missile launch tubes since those are generally regarded as being accurate. The interior might not be accurate but I've read that it's certainly busy enough and looks impressive when complete. The overall shape of the exterior, however, has been said to be fairly decent. Is your interest in the kit more as a collector, a seller or a builder?
I'm not a big sub builder (I've only built two and they were both Dragon kits) so I'm hoping others can chime in.
Welcome to the forum!
Eric
