Yep, +1 rcsimulations - even though the website is a bit pants, the service is top notch.
I'd ordered mine from RC last week, and it arrived 10am next-day!
Give them a call before you order though, just to check that they have them in-stock. I did the same thing and the lady on the phone said they only had a few left - I guess a few people have seen
this and bought one.
Also, if you do order, make sure you read the confirmation email that they send out, because for some reason (security I guess) they ask you to email or call them and confirm the security code on the back of your credit card. Nothing will get shipped unless you do... I called them and it was sorted in 20 seconds, so no big deal.
Oh yeah, and the Track-IR works really well with ARMA2... especially in flight. Takes a bit of getting used to at first - after two hours of flying in ARMA2 I did a bit of web browsing and found myself trying to scroll the page by tilting my head back ffs!
That aside, if you are planning to do a fair bit of ARMA2 or some general flight/driving, then I'd definitely recommend it.
* Yes that was my first post, and No I don't work for them.
