cheap vs expensive flexplate

so i called acc boss hog and the weighted convertor that will work best for my car is 470 bucks. and it will use the stock flexplate. (4200 stall)

the other option is the bm plate and hughes convertor. about $310 (best, more tougher bet, but only 2000 :banghead: stall)

the lower stall boss hog is a more reasonable $325, 3200 stall but once again be using that stock plate, and wont be the high stall that i want (he said for such a light car, the stall drops from advertised stall) but, is looking to be my best option
