Would you recommend a monopod brand/model for me? I use a D70s to shoot basketball, football, soccer, and tennis. Nikkor 70-200 f2.8 is my standard lens. With $3,000 invested in my camera, I would like to get the right monopod. Under $100 would be nice (for a change). I'm not good enough to quit my day job (unlike most of you guys). Thanks. You guys always give me more information than I thought to ask for. I'm 6'2".
