That said, your method may vary. Lots of folk here like their Giant bikes. Definitely try before you buy. As FREECLOUD says, every bike maker has their own definition of size - not every 43cm bike is 43cm...
If it doesn't fit, you're not going to ride it, no matter how good the price!

If God invented marathons to keep people from doing anything more stupid, the triathlon must have taken Him completely by surprise. -P.Z. Pearce
My advice would be to try one on at a bike store to be certain that the frame size is right for you.
I found a used Cannondale on Ebay, a size 43, and almost bought it for a steal. I went and tried one on and found the 43 was way too small! However the Trek that I just bought is a 44 and fits perfect.
Apparently different brands run different sizes, although you would think 43 cm is 43 cm. It depends on where it's measured from and to (that's how it was explained to me, anyway)

"We run, not because we think it is doing us good, but because we enjoy it and cannot help ourselves...The more restricted our society and work become, the more necessary it will be to find some outlet for this craving for freedom." -Sir Roger Bannister, first runner to run a sub-4 minute mile
What kind of shape is it in? I bought one earlier this year, it's my first road bike! It had been used by a young woman who did triathlons and had a injury and could no longer bike. The price sound right!
