I have a Scoutmaster JMW9 combo. I have owned a Dynavector 20X-H, a Shelter 501MKII, and now a Zyx Airy III. All work well. The better your set up, the more you'll get out of your cart. I enjoyed all 3 carts. The Shelter was smoother and more detailed than the Dyna, and used is only about $150 more than the Dyna. The Zyx Airy III cost much more($1400-2700) and requires alot of attention to detail to get the most out of it, but if your set up has the resolution it is worth it.
