Whats the best Torque Converter

[Brady91 GT]

Ok im gonna buy a higher stall torque converter for my rebuilt AOD. The tranny guy said i should go for the TCI Streetfighter 3000 to 3400 , tci said on average itll stall up around 2800 to 3200. If i buy the stall converter im gonna have to get 4.10 gears, so im kinda hurtin for money. TCI wants $425.00 for their converter. Do any of you guys or gals know of a cheaper converter that as good as tci but cheaper?? Or a better converter thats around 400.00 but is better than TCI? Please if at all possible please help cause i need to get one so i can get the tranny in. Also 1 last thing how much will a stall and 4.10 gears help my stang in the 1/4?(it has flows and a k&n) Well thanks a million in a advance to whoever replies.
