If you want the best....get the Pitbulls!
I have Pitbull, Handy, and LP stands and the Pitbulls are the best IMHO. That being said, the others are still good stands and the Handy stands are the best bang for the buck although the front stand is not as stable as the Pitbull.
If you want to be able to remove your wheels, service your forks, etc. then you will need a front stand. If you just want an easier way to adjust and clean your chain then i would just buy the Handy rear stand for about $80.
Also, i'd highly recommend the spooled stands b/c they are more stable.....you will need to buy the swingarm spools in addition to the stands for this option.
