Most gurus here have already answered questions about the sticks, lemme share my input:
• Phyurix: on the other hand the Westerners designed it following the official SF4 Taito Vewlix cabinet panel found in Japanese arcades. So these are what the Japanese are using, down to the stick, buttons and button layout. And you are right about the price - costs a bomb and I will later on comment on the experience!
• Rockfire PS2 to USB adapter: this is what I am using now, and there's no visible input lag.
• The TE uses the same Sanwa JLF stick as the HORI RAP3. The 2 main similarities between them, which comes to mind, are the buttons and stick. TE has a cord storage compartment behind, lock mode for the turbo buttons, convenient placing of Home and Start buttons (at the back) to prevent accidental presses when mashing (= instant disqualification in US tourneys), exact button layout/panel design as the Vewlix, removable legs to enable table mounting via screw, etc.
• The Virtua Stick High Grade (VSHG) has been discontinued by SEGA. Only option is eBay where a lot of people are also looking to obtain one. Solid piece of stick and I personally prefer it over the HRAP3 for non-Tekken games alone
• senzr: nice weapon of choice there. Not to sound anal but the 'SA' = SAnwa Edition. HORI names their sticks this way. So 'SE' = SEimitsu Edition. I failed. That sounded anal of me

• Eddy: Nice deal. You can get 2 HRAP3s with a TE

Actually it's true the US buttons are better and more responsive than Japanese counterparts. HORI proprietary nonetheless, still good. Oh yeah.... DAMNIT Eddy congratulations
THE STICK!
I second TristanX to be the next TS for version 3!
Nice detailed explanation on those sticks bro ... it surely will aid people in choosing a stick for themselves ...
