A good decision in my view Ender. Where are you based? I may be able to suggest one or two places to visit. In any case travel around and just sit and watch a class at various venues. It is easy to see and appreciate a well run club and a skilled instructor.

Martial Arts are the same as any other trade - there are 'cowboys' out there. Watch carefully its easy to pick them out.

If you see a good class, a reputable instructor will offer you a free 'taster' lesson. You can then take it from there.
