Is anyone using a SpaceBall 5000 USB with SW2010?

I'm using SW 2010 SP1.0.  I currently have a SpaceNavigator, but would like more programmable buttons like an old SpaceBall 4000 I used to use.  Our company won't pay for new SpaceExplorers/Pilots, so I see \$50 SpaceBall 5000's on Ebay and would like to know if they work before I spend my own money on one.

I've searched the forums and have only found info for the SpaceBall 4000's on older SW (2007-2009), so again I'm hoping some of you have got the 5000 to work in 2010.

Thanks in advance,

John
