I don't see how the WH can be an immersion killer while a Fighterstick cannot. If you even plan on playing F-16s or A-10s down the line, the WH will pay for itself straight away.
Quality-wise, it is plug-and-play. I've had mine since release and it's not given me any calibration problems so far, though I had a problem with the stick base for a while and had to return it. Aside from that two-week trouble period, it has been performing 100% all the time, every time. People say CH is the same, but I've not tried that so can't comment there.
I've had a Saitek (piece of crap, except for the rudders), Cougar (modding nightmare, good for practicing soldering and electrical skills), and Warthog (good for actually practicing flying, fighting, refuelling, and bombing skills).

I just classify this purchase as one of those long-term-return ones. Do you buy cheap that breaks down early and have to upgrade in a year or so? Or buy pricier items that will last longer?
