ShadowGray,
What "size" are you? FWIW I rode the pure T crap out of Raleigh 3 speed for years (197? model, paid $25 for in 1982)...still have it over 25 years later and it is still ridable. FWIW you will have 2 main issues with a Walmart bike. 1) You will need to go over it with a fine tooth comb, and basically do a complete overhaul prior to riding it. 2) They only come in one size...for the most part.

Quite often good used bikes are available at an LBS. I have bought several that way.
