Logitech 3D Pro, $29.99 brand new at most.
This is the stick I use currently.
For me a 3D Pro seems to last about 12 months before it loses its center for whatever reason.. I think it is a great stick regardless.
It's a get what you pay for thing, but its not bad.
My first stick was a Cyborg FLY 5 that shyt the bed on me in the first month I had it, it wasn't too expensive ( only 69.00 ) but since it died so fast I went with the even cheaper logitech and it was wayyy better.
I'm looking to try out something different though so I will be moving from the 3D Pro soon.
