I have and use 2 Saitek BIP's, and have no complaints with them. They really add alot to your simpit. Heres a vid of my setup with both BIPs in action among my other saitek gear -

Yes they are a bit pricey but well worth it. I purchased a second on as there are many indicators you can setup, more than will fit on one BIP.
If you have any questions let me know...
