I believe my SVT tri-ax is sitting in a decoratively-wrapped box under the conifer upstairs... CAN NOT WAIT.
I had the "STS" for my original MTX75 and it changes the feel of each shift drastically, for the better I might add! I've had the MT285 for 6 years and I've missed that shift-feel ever since; Iblew up the 5 speed and sunk ALL my money into the swap, so I barely had the loot to finish getting all the parts, let alone fun-bits.
If you have the means, and were on-the-fence about it: just get it. If you regret the purchase you'll find it will sell very quickly in the BST section! You really can't lose...
