HardRacing sells the TTX for ~1200 & the 25mm fork kit for ~1500 (including installation at Ohlins, iirc), and their prices/service are among the best around.
That's still a pretty damn good deal. Tempting, but I guess I should wait until 'regular' employment before dumping more money into the GSXR (who am I kidding - I'd still probably do it if I hadn't already picked up a Penske 3-way...
).
