whatever you do, i strongly advise against binding with ace bandages. i did that for several years in highschool b/c i couldn't afford a binder and i didn't actually even know that they existed.
ace bandages restrict your breathing and can really damage tissue, not to mention really mess up your back!!!
tape is also a very bad idea (although it seems like another very inexpensive method). it can tear off skin on removal and irritate it (some more than others) during use.
personally i am fairly pleased with the products from underworks, but have heard great things about a binder from mango used by (and made specifically for) larger men.
This vest is recommended for large-chested guys, featuring double layers of lycra in the front for maximum support, and comfortable stretch material in the back. It pulls on easily over the head, wraps around the torso and fastens firmly with velcro on the left side.
happy hunting
