WTB Box Stock Clone Package or Chassis for Box Stock Clone

Hate to make this my first post, but I am a student in the Sacramento area that is looking at getting into BSP racing. I am looking for either a BSP package that is relatively cheap and still conforms to the BSP engine rules. Alternatively, if anyone has a chassis that would be great for BSP racing I wouldn't mind going that route and building up the engine myself. Basically looking for a budget friendly way to enter into Kart racing while still in school. Was thinking tag but the tire cost worries me. Let me know if you guys have anything. I am from the Bay Area so I travel back and forth between Sac and there all the time. Thanks.
