Strain Gauge Cartridge info requested

Over the weekend I picked up a Win SDT 10.2 strain gauge cartridge and controller at the Denver Audio Show (great show!). It was recently retipped by Van Den Hul and sounds wonderful. I have another body that needs a new cantilever and stylus.

A Google search turned up only two minor references. Please respond if you have any info. on the technology and/or retipping service. Thanks in advance, jeraldrc.
