904 torque converter recommendations

1969 torqueflite 904 with a stock converter. Believe stock converter stall rate is around 1100 without me physically testing it at this point. I know converters are very expensive. I’m looking to increase the stall to about 2000. I know you have to implement a few specifications on your specific car to get the right amount of stall for a new converter.
Has anyone installed a 2000 - 2500 stall converter in the past few years for under $350 ? Which make and model do you recommend in that price range. Elaborate on your satisfaction and what the changed characteristics were like. I know good converters cost more. But, I just want to increase the stall a little for the least spent.
Is it necessary to put a new converter on that is locking ? What does locking do, act like a rev limiter ? Being small blocks are externally balanced. Is it necessary to buy a converter that is balanced with weights ? It’s a moderate small block engine with about 300-350 hp. Small performance upgrades, etc.
