You can try front squat, with smith machine if you aren't comfortable with it. I normally don't recommend squat unless they are serious weightlifter, powerlifter or bodybuilder. For all intent and purposes inclined leg presses will build your leg faster than squat, you can push more weight, psychologically you aren't worry about losing balance or any discomfort squat brings on you. Anyway you need quite a thick traps to squat heavy without hurting your self. If your traps aren't as thick you should use padding until your traps are build.
Wow, this is flat out horrible advice.
You should avoid smith machines at all costs. No matter what exercise you do on them, they force your body into a very rigid and unnatural motion. This is especially problematic with squatting. Likewise, the leg press is NOT a substitute for the squat. It again forces you into a rigid and unnatural motion, and it removes your back, balance, and coordination from the exercise. In fact, I'll make it simpler: don't bother with machines of any kind. They are not nearly as effective at building strength, they don't let you train your balance and neuromuscular coordination, and they are not any safer.
Also, with the possible exception of people with pre-existing injuries, EVERYONE should squat. It's one of the most effective exercises for the human body, whether your goals are to gain muscle, get stronger, jump higher, or whatever.
Finally, if your neck is hurting, you're probably not holding the bar in the right spot. It should be sitting on your traps, and no, you don't need huge traps for this to be comfortable, you just need to position the bar properly. If you can't get it to work with a high bar position, switch to low bar squats, where the bar is essentially sitting on the back of your shoulders and no where near your neck.
