There are probably a bunch here who do Judo and/or Brazilian JiuJitsu (BJJ) and/or MMA and/or Boxing and/or Muay Thai or are interested in starting.

Grappling is very important and Judo is pretty inexpensive while BJJ can get pretty pricey. I'm just curious, how much would you pay to learn grappling from true Black Belts of the sport such as ... ?

Well... I pay $139 a month to learn from Kenny Florian and his trainers. So... about $139 a month, since I can't afford more than that.
