>>>well OK I was lucky but if you take your time and are stingey lol
>>>10 y/o freerace, $150 Sail free here

Boom secondhand $180
>>>mast secondhand $400 $800 to do warp speed in 14kn and just as it gets too much I can just dog out on wave gear.
$180 for the boom and $400 for the mast? I guess it's a carbon boom, and an RD mast.
An aluminuim S/H boom, and a STD mast would save you another $400 and you would still enjoy it the same
But...you are right. Windsurfing equipment is more resilient.
I started stingy, bought a 6 years old kite for $150...guess what, it leaks...
I guess the twin-tip kite board is more resilient than a windsurfer, but the kites certainly don't last.
Having said that. I'm not ona brink of selling my windsurfing equipment, just complementing it with a kite in order to get more time on water.
