Try yard sales and flea markets. People are Spring cleaning and down-sizing. Be patient and you may find a great bargain. Check your local newspapers for yard sale ads - they will give a overview of what will be in the sale.

Hobby shops - search for locations in your area by using http://www.switchboard.com

You probably have already "salivated" over these - http://www.nitrorcx.com/ WOW!

You can get exceed rc cars for 99.99 dollars. They are pretty good but try not to break parts it is expensive (Shipping parts over). There are no GOOD cars that you can buy for $50 unless it is used. I was like you before and regret buying those cheap cars. the best value for you money is a traxxas slash. it is cheaper in the long run. if u break parts u can get parts at the hobby store for 2.00 without paying a horrendous 10.00 for shipping. The traxxas is also more durable, easier to fix, better preforming and you won't need to replace the whole car every year. Cheaper in the long run!
