How does an Aura Bass Shaker Pro compare to the cheapest Clark Synthesis tactile transducer? Is it worth the extra money? Better build, better shake per unit? If I go through all this trouble I don't just want an expensive joy buzzer in my seat

, but I don't have the cash to get a Buttkicker or high end Clark.
Supposedly Clark Synthesis is now fusing the basic Silver TST229 and the Gold TST329 into the TST239 with the same $100 and under price of the TST229 and the power output of the TST329. I don't know when they'll be out, but they were announced at CEDIA '04 for a ship date of late October.
If it's true that the specs are relatively the same as the TST329 then wouldn't that be worth waiting for? Hmmm...
