Another converter thread

In the process of getting a better converter there are so many options have no idea what to get. Have contacted two places, the first gave me a converter with 1800-2000 stall which seems low, the second place said yeah we have one it will be this much $. Emailed them about approx stall and never got back to me. So still up in the air on what to get. I know some people get high stall and say they are fine on the road this is not what i want i am guessing i want at least 2300 rpm or so stall. Just something that is a little better out of the whole and not a race converter. Anyone have recommendations or have similar set up? Here are some specs of the car.

This car will be driven 98% on the street. Cruise at 55mph is about 2900 rpms i would like to be able to cruise at this speed for hours if needs be.
Converter in it now give a 3rd gear launch of 1900 rpm stall.
