Here is a low budget balancer idea that is easy to build.
Buy a great planes finger balancer for less than 5 bucks. steal your kids stereo speaker magnets. (you deserve the peace and quiet!)
knock together a 3 piece wood frame that will hold the magnets 12 inches above the base of the wood stucture. It should also hold the magnets 1/32'' wider than the finger balancer... just use the TLAR method ...you know That Looks About Right. the magnetic field will hold the balancer up but one side will not touch the magnet you can also glue a piece of THIN plastic to the magnets for additional friction reduction. It worked for me until I bought a ready made one at a sale.
