Daniel,
Make the trip.
I took my clays gun there for bore-matched choke tubes. They were really nice to deal with and the choke tubes are excellent. I also purchased one of their customized 390's and loved it until my daughter talked me out of it (she seems to do that with a lot of things). Their trigger work was great.
Just be aware that it's not the easiest place to find. The sign out by the highway, at least when I was there, was for their machine shop operation and did not mention Seminole. I would call for directions.
