I have a Super Ricohflex with an 80mm f/3.5 lens. Shooting wide open with a shutter speed of 1/25 sec. I can take available light photos indoors on Portra 800 (I installed daylight balanced bulbs in two rooms in my house) and they end up being underexposed by about a stop. The latitude of the Portra 800 is more than enough to get a usable image out of the shot. I bought one off of eBay for $50, and when I got it, the focus was frozen on it. Mark Hansen agreed to take it off my hands and send me one he had all ready to go for the cost of what he would've charged me to fix the one I bought off of eBay. It's a sleepy little camera with 6 f/stops (3.5, 4, 5.6, 8, 11, 16) and five shutter speeds plus "Bulb": "B, 1/10, 1/25, 1/50, 1/100, 1/200"). I can use it indoors and outdoors too. I'm still using the one Mark sent me two years ago.
Glad to see you found a TLR that meets your needs. It's a fun style of camera, for sure. I love mine and it's a good little medium format camera. Way better than some of the box cameras.
Now if I would just get my act together and get the adapters I want to be able to shoot 120 in my Kodak Brownie Model 2A...
