There are several High Tides and a couple of older Bug Busters on the SC craigslist which are similar in style. My buddy who has a cabin at Sumphole on Santee has a Big Buster from the 70s with stick steering and a 20 Merc.
The High Tides are a bit more stable and roomy than the BB and will handle a 40 HP a little better, but there are several other similar boats and they pop up on the SC craigslist from time to time. I've even seen a couple of Panthers on there(put Panther in the search bar on Craigslist). Just be careful to insure the floor and transom are solid. That was a weak point on some of the older ones. My buddy needs to replace his floor before he can use his again.
