If you want the VERY best stick and throttle combo for a HOTAS, and don't mind some tinkering:
Flightstick / Gimbal :
VBK Fat Black Mamba (when it comes back into production, sold out at the moment) - you can replace the handle with a Cougar or Warthog handle at your pleasure.
The Fat Black Mamba has the best quality, most advanced gimbal of any flight stick I know of. I only have a Cougar (now disassembled) and Warthog gimbal/stick, but I really want the VBK Fat Black Mamba!
Throttle :
The Thrustmaster Cougar throttle is the best in my opinion. The benefits of the old Cougar throttle is the ergonomic design (your hand fits it like a glove), and most importantly for me: there is an ANALOG thumb-stick axis, not just a digital hat. I use this for total fine-tuned control over lateral and vertical thrust. A hat is digital, and will only allow you to control it digitally (on / off) and not with fine tuning, similar to when you press the keyboard buttons. However, I would recommend you replace the pot sensors (based on friction, wears down) with magnetic hall sensors (longer lasting, zero wear), and that requires a bit of tinkering from your part. (google "Cubpilot's hall sensor kit")
If you just want a very well manufactured consumer HOTAS, that is cheaper, I would go for the X-52 Pro. But I would be weary of Saitek's support and driver issues. There are some stories about it. Hopefully they have learned and gotten better. But for example, if you were unlucky enough to have bought an X-65F HOTAS like my friend did once, you would be left out to dry with zero support. They've discontinued it and refuse to give proper support to those who bought it. My friend bought a Warthog instead.
A full Warthog HOTAS setup is perhaps the easiest solution to acquire if you want a high quality HOTAS, but you should be aware that the Warthog throttle (in contrast to the Cougar throttle) is not ergonomically designed - your hand does not rest comfortably on it. It does not have an analog thumb-stick, only hats.
You can find the Cougar throttle on Ebay. Though I've not seen one pre-modded with hall sensors.
