Where are you sourcing the magnet from?

10mmx3mm N35 neodymium magnet with a 0.118"/3mm countersunk hole. Ebay seller have them for very cheap (maybe $0.10 each) or K&J magnets should have it.

Doesn't the new SRX Encoder have the same interface? Granted, this design saves teams a couple of dollars if they're willing to do the fabrication, but I don't think it's unique.

Oh neat, you're right. Well it is unique among IC's anyway; most are either quadrature or absolute, not both. This is the cheapest IC I found that has both (ironically it is also one of the cheapest pure-quadrature hall effect sensors).
