I just posted this on another thread but thought it might apply here as well
one other thing to keep in mind is the set up after you plug it in.
I've just been wrestling for a week to get the Turbo Twist Hi-lo Spinner to work properly.(Same issue with the TT2) You need to up your mouse poll rate (which can be difficult depending on your OS) otherwise you get crazy backspin because the resolution is so ridiculously high (and unnecessary in my opinion, unless your building a dedicated Arkinoid cab, and I mean really do you need high resolution spinner for glorified Break-Out?)
Both the the Apache and the Ultimarc Spin-Track work without that hassle of changing the mouse polling rate
I don't have a Tornado so I don't know about that one But I'm pretty sure it's a standard resolution spinner, so you wouldn't have to mess with the poll rate
I'm not saying one is better than the other, they all have advantages and disadvantages
and all three vendors make quality products and have great customer service
