Title Boxing Heavy Bag Wallmount Hanger Review
The problem with your normal type of heavybag stand, is that they usually feature legs that come out to the side of the bag - which could be problematic if you're looking to practice some low leg kicks. So any type of system where you can find a way to hang your bag from a wall or ceiling would probably be best. Not everyone has the option to go f'ing up their walls though.
As for bags - I believe either CSI's or Ringside's powerhide (their synthetic leather) bag filled is on sale for $100. It's probably worth checking out.
