Buy a used 14m-16m waroo for around $400 and one small C kite, or buy a couple of C kites. Do not under any circumstances pay more than $200 for a complete C kite with bar and lines. I woulld opt for one 14m-16m waroo over 3 C kites. Watch the ikitesurf classifieds and ebay.

Here's what I sold my kites for:
