I ran across a NSW located DSLR fitler mod supplier on ebay.

While they write the ad as an IR conversion, the filters used and offered are suitable for UV/IR Cut and you get to pick the IR Cut wavelength of the filter used. Reading through all the FAQs is important, if your interested. They remove your old filter pack and insert the new one - apparently.
This seems to be a real conversion (you send them your camera) and not just a filter supply place. For $99 it seems pretty good value compared to getting a simple LP2 filter removal done at a camera shop (typically $150 min).
