Looking for a tube chassis

How fast do you want to go? If we are talking 10.0 and slower by all means buy a mild steel kit and buid your chassis. If we are talking about 9.5 and faster or chrommoly have a pro build it. I wouldn't trust my life or having it rejected when time to certify plus a tube frame car built by a pro will sell way better than a home built one. Nothing wrong with store bought, I would do it in a heartbeat.
