These above (Az-1 hand controls, you can google them) are barely over $300, and you can install them yourself in under 5 minutes. As a bonus, you can also take them off your car and put them on (almost) any other vehicle in 5 minutes. To install you just slip the feet around the gas and brake pedal and tighten it down with the wing nuts attached to the feet. Four "bolts" and you don't need any tools. I routinely get to the airport, pop the hand controls off and stuff them in my baggage, get to a new city and reassemble the hand controls so I can rent whatever car I want instead of whatever car the rental company decides to put hand controls on (if they even bother to actually have a hand control equipped car ready after I request it).
I bought a set in 2007 when I was injured and have used nothing but these (well okay, I did fly out some places and use a rental car with it's own hand controls a few times) since that time. Cars of mine that they've been on are a Toyota Camry, Toyota Solara and currently on my Honda Accord. So they've outlasted two of my cars (one of which was totaled while I was driving it, the hand controls were fine and did not injure me in any way).
I did run into one issue. I rented a Dodge Challenger and drove out of town (it did fine with the hand controls), but when it rained I realized that the Challenger rear tires were bald (surely this had nothing to do with the burnouts I was doing on the way to the mountains... right?). So in the middle of nowhere I had to swap rental cars and the only option that would work for me, my lady friend, and her dog was a Jeep Liberty (or something like that... some kind of Jeep). This vehicle had very large (very plastic) bulky pedals, so the feet of the AZ-1 hand controls wouldn't fit over it, it just would not work with this kind of vehicle. But in my experience that's like one out of probably ten or fifteen cars that I've put the hand controls on without a problem (between rental cars, friends and family's cars, and the three cars I've owned in the past few years).
It blows my mind that people pay $1600 for hand controls. I mean if it works for you and you've got the money, that's great, I guess, but I've had no problems on the vehicles I own with my $300 hand controls and they're still going strong 11 years and probably 200,000 miles later.
If I won the lottery today and went out and bought a top of the line Mercedes S class coupe for $200,000 I wouldn't put my current hand controls on it, however. Such a nice car would surely deserve a brand new set of AZ-1 hand controls, but the point being even if I was fantastically wealthy, I would still use these hand controls, I've gotten used to them after all these years I guess.
(note, I'm not affiliated or paid by whoever makes these hand controls in any way, just a big fan of the product, which I guess is obvious).
