When shopping at various equine trade shows, be wary of "gaited" equipment.  There is no magic bullet - either you learn to ride well enough to keep your gaited horse "gaiting"  or you don't.  So called gaited equipment, magic shoes, and any manner of funky gizmos won't do anyone any good if they don't understand how their horse moves, how it is built and the types of saddle and pad combinations that work to keep a horse and rider comfortable.  I have saddles of most every type and description from full bars to semi-quarter bars to arab trees to flex-tree to treeless.  A customer brought in a "gaited" saddle (quite expensive) and sold it for a much less expensive flex-tree type that I use every day.  We finally found a horse that the gaited saddle would worked for - however, a Bighorn synthetic saddle fit the horse and rider better. 

The same for special bits.  Either the horse is broke and rides in most anything - or it's not.  For showring work a horse should either travel in an easy broken mouthpiece (no double wires or knife-edge please) with less than an eight inch shank (rein to headstall) or a standard solid mouthpiece adapted to the horse - meaning space for the tongue, comfort for the bars, and an easy curb.
