I think that joeychevron has a good point there...

I am building a spinner myself as my first robot, and it has turned out to
be EXTREMLY expensive......but it has also been very fun to build, so I
still dont regret the choice of bot.

My advice would be that if you really WANT to build a spinner, then you
SHOULD build a spinner. I think that the whole point of building a robot is
that it´s a fun hobby, and I dont think it would be as rewarding to build a
kind of bot you don´t like. But I am not that experienced in the sport, so
you should probably listen to the other builders instead of me....
