What are the cheapest skates with a replaceable blade (runner)?

I have a pair of Bauer ONE20 that I love, and use for recreational use about 2 times a week. I'm gonna be playing for my high school team and they hit the ice around 5 to 6 times a week. I like to have my skates sharp, and my ONE20s don't have a replaceable runner.I really like the Bauer Supreme line but if i can find a good skate for a lower price I'd buy it. What are the cheapest Bauer Supreme skates with a replaceable runner? And what are the cheapest skates available with a replaceable runner?
