hi Des,
i've learn't to kite with a tribal 2, no problems, and no repairs needed since november 06. If you spend time looking after your kit, packing up etc, whatever brand / make then it won't need fixing... If you can fly the kite without crashing it every 10 minutes on the water and beach, and you learn when it's necessary to use your safety release, you can avoid most situations that break kites. I've been very pleased with my tribal, I don't think it's any more fragile compared to any other kite on the beach.
'Overpowered' is dead right - fly the kite lots and learn how it behaves and misbehaves in strong and light winds - you learn loads about the kite in low winds, and it's more forgiving if things go wrong!
good luck
