You can buy them cheaper than you can make them if you shop around for a deal on some used ones. I bought used whal skis from Jim Dimmerman a Loooooong time ago that looked very good. He sold me track and ski's and gave me a very fair deal on them because he wanted all new stuff for what I think was a shootout in Brainerd at the time. Just look around. Or maybe somebody can lend you a set to make a duplicate copy from. Good luck, asphalt racing is fun.
