Torque converter questions

I think I decided what kind to get:

Has anyone used these before? I'll call them on monday and get some more info on it. Not sure why it's 2,200-2,800 when other ones I see have one stall rpm.

Is it really nessecary to run a trans cooler even though it's not real high of a stall? I could see using one for a car thats more race than street.

I've never run one of their converters but $191.00 sounds a little too cheap for a quality converter to me,sounds more like the price for a generic off the shelf fits anything item,trust me you can benefit from a good quality converter,over a cheap poorly made one any day..as for a trans. cooler that is always a good upgrade along with a deeper trans pan to aid in cooling also..
