I have an old Marcy fitness "station" that has a pec deck, pull down station, and leg extension you speak of, and the seat adjusts to 3 different heights. I'm 6'3 and can do extensions on it.
I bought it at ****'s sporting goods a few years back on sale for a bit under $200.
Only thing that sucks is I hafta put DB's on the weight stack since it only has 100 pounds, which is good for awhile!True story:
I give a f**K!!

There are a dozen different pieces of equipment I would invest in before buying a leg extension machine. I'm not going to say its a useless apparatus, because it does serve a purpose, but for the development of the quads nothing is going to give you better results than some version of the squat - olympic squats and front squats possibly the most quad involvement. You're better off building a sissy-squat apparatus, to replace the leg extension.

Yep, check Craigslist and ebay. You should find something suitable. Also, there's no difference in leg development with front or rear squats. It just comes down to which is more comfortable not which hits the quads harder. They both hit 'em the same.

Is there any study showing the difference? Because the one I saw didn't differentiate between the styles (olympic vs. powerlifter) of squats. It just concluded that the leg muscles get hit the same regardless of front or rear bar placement.

I can't say I've seen one where EMG's were done, I can take a look later this week.
My rationale is based off the biomechanics of the change in bar positioning changing the center of gravity and torso lean. A lower bar allows for a greater torso lean, thus recruiting more hamstrings. A higher bar, when performed correctly, means a more upright posture, placing more emphasis on the glutes and the quads.

Derick, i'd say given some of your other joint + flexibility issues, you may want to avoid leg extensions. They place a rather different strain on your knees and i'm thinking it may not work that well for you long term. I've got knee arthritis, and I do them (and fairly freakin heavy, was doing single leg ones for 110lbs) but as was said you'd be better off investing in something squat related.
something like this perhaps
And honestly, given the timing, you may want to put off buying it for a couple months. craigslist is basically flooded with exercise equipment from february thru march, as all the new years resolutioners realize they haven't touched the damn thing since buying it for themselves for christmas. So prices are most negotiable then

Will help a little with over head presses.
You should also strengthen your mid trap fibers, lower trap fibers, rhomboids, and external rotators.
See if you can find a similar article about improving hip flexibility and function, namely, releasing the hip flexors and activating the glutes.
