Thanks for the info!

I just saw what looks like a nice single speed Dawes bike on Ebay. Got some reviews by googling this, and found that the parts on it are cheap (can't tell if they are not suitable for riding, or if people who say this are the types who normally get $1,000 bikes. haha). It's only $200 even after shipping. I was thinking I could buy it, save up for better parts, and customize it later. Instead of it being one huge amount of money upfront.

But I guess, yeah, I should really hold off for a bit til I can do my homework and just try to find a good deal somewhere instead of purchasing something online.
