I take classical lessons and really love the style, but I don't actually have a classical guitar. No one wants to hire people my age so I don't have a job, just $50 per month for allowance. Any suggestions for a good, dependle nylon string for a very affordable price?

hm..I would just look around for something used; at the couple of guitar shops around me I've seen a number of classical guitars for under 200 dollars..I almost bought a nice slightly used one for about 210 the other day. Maybe ask your parents for a slight advance on your allowance?
You should definitely look into buying a used one. Keep an eye on craigslist and maybe ebay too.
