I'll also warn you that while they are great bikes, a symetry may be heavier than you want for a triathalon. If you don't want to spend a lot of money, and are sure about your size I'd look for a used trek1000, 50 or 52cm. There are tons on ebay at good prices.

If you really like it, upgrade to a trek5200 or its equivalent.

So, to answer your first question is this a fair price, I would say yes if the condition is as stated. But, I do not think its the right size for you. Out of curiousity, how tall are you, and do you know your cycling inseam? How did you feel riding the 50cm bike in the shop? What model was it?
I'm 5'4" - I don't know what my inseam is (can't find my stupid measuring tape!). To be honest, I was surprised that the guy at the LBS said I could go to a 52, because I barely had clearance while standing on the 50. I don't remember what model it was, unfortunately. I thought the 50 felt pretty good, but this is my first time with a road bike, so I don't really know what I should be looking for. He said the seat was a little bit too high, but it was as low as it could go without them custom cutting it, so I couldn't get an exact fit.
