I'll write one about mine to give you an idea:
speedlink black widow

The Black widow is a great first joystick. It has a nice stick that's easy to hold thanks to the hand rest on the bottom of the stick. The stick has 4 buttons, a trigger at the back and 2 on top and the 4th on the side. These work great for weapon selection and firing, the trigger obviously is set to fire guns only, this way I can shoot my guns even when other weapons are selected. I use the small round one on top (F4) to toggle through my weapons and the one above (F3) to fire selected weapon. The button to the side (F2) I have set as flare's so that I can shoot flares even if I don't have them selected, always useful in a dog fight or ground attack mission. To round all the buttons off it has a little hat switch for changing your view in the cockpit, again great for dog fighting and seeing where you enemy are with out taking your hand off the stick or throttle. The only problem with the stick is that it has a small dead zone, that makes it hard when you want to make small adjustments while flying or landing, but you do get used to it after a while.
The throttle is a great little addition to any stick, and with the Black widow you get a nice little throttle that fits nicely in your hand. you will also find the rudder control here on the back so that you can use your rudder while keeping your hand on the throttle.
In addition to the programmable buttons on top of the stick, there are 4 programmable buttons on the base, they are big so you can press them with out looking down. You can programme them to do anything you want in YSFlight I have them set to Gears (F5), Radar (F6), Reverse thrust (F7) and bomb doors (F8).
the Black widow come with suction cups that clip in the bottom, but to be honest they are not needed as the stick is stable and even the roughest movement of the stick fail to move it.
The only thing that lets the joystick down is the dead zone on the stick. And the only feature that doesn't work with YSFlight is the vibration but it's not missed. A great starter stick, that has lasted a good 3 years now.
