OK I am a big PitBull Beeoootch, so I would say buy PitBull, they are worth every penny from a durability and strength standpoint. When my bike is in the air I mean you can physically shove on the side of the Busa and there is No Flex, no wiggle, narry a twitch and to me that means a lot. They will also adjust to fit different width swing arms. My .02, you get what you pay for... As for spools or Paddles. IMNSHO you gotta go with spools, they are cheap and really lock your bike onto the stand! I feel they are the only way to go.
Front stand, definetly look into the stem stand not the fork stands but if the price difference is huge and your pretty sure you are not going to be messing with your forks then the fork stands will prolly work just fine.
