I had the same problem a while ago. Most of the ones availible are cheap POS. If you have the time and expertise, or can find someone that does, you can build your own from a PIC microcontroller. Microchip even gives the software away, and the schematic. (One note about the schematic is that is has the clock and data pins to the PS/2 port backwards.)
I'm just glad these stupid TLD's might be stopped intirely. WTf is the difference supposed to be between.com and.biz? It just makes another TLD each company will pay out $35 / year for.

Microchip's Application Note
Microchip even provides gives out samples for free, you just need to find someway to program it.
I assume that you were trying to right out the quadratic formula, in which case you got it wrong. It should read: "(-b +- sqrt(b^2-4ac))/2a = 0
