Hey, I've fallen completely in love with the Pro Line Rhyno and I want to buy 3 or 4 of them to practice with. Does anyone know of either:

a. The cheapest place to get them
or
b. A place that offers discounts for buying 3 or 4 of the same disc (this would kind of fall into the first category, but you know what I mean...)

Any info would be greatly appreciated! If there is any individual out there willing to make me a deal, I'd be down for that too. Thanks!
