torque converter builders

first call I made today was to TCS
they suggested their off the shelf unit, an 11 inch pro street unit
2400 flash stall, $445.00 plus about $80.00 shipping

Second call was to PTC
They suggest a custom build 9.5 inch unit that stalls at 3200
They said the parts umber ends in 200 meaning it is tighter then most?
$475.00 plus some 30 odd bucks shipping
