I have a set of Keeneland brand fleece polos that are pretty nice, and have held up well for three years of occasional use. My standing wraps and quilts are Milepost brand (from TSC), and I can't complain.
No matter what brand you buy, be careful about doing the actual bandaging carefully and correctly. The last thing you want is to wrap with too much or little tension in the wrong place. If you don't have a great deal of experience with wrapping, find someone who does and have a "lesson" or two before you try on your own.
