if i were you i would keep looking around
although you can do squats and many other exercises on smith machines, i and a lot of people i know really dis like them as it doesn't give you the free motion that a rack and barbell does. In saying that i do know people at gym who love the smith machine and swear by it, although either way id suggest you still have a look around, a gym with a squat rack shouldn't be too hard to find
good luck mate
