its a nice bike with pretty good components and a good price.

the only possible issues i can see are:

Fit - are you fairly sure that size of that model will fit you?

Support - if you're a complete newb you will be taking it to the LBS a lot for adjustments that are usually free if you bought a bike at the LBS.

Ebay - if something doesn't work out right do you trust the seller will help you?

However, if it's new its not likely to have anything expensive go wrong with it for quite a while. And if you're a newb you won't notice minor differences in sizing, so if you're anywhere between like 5' 6" to 5' 10" that bike might fit just fine. And the seller seems to have good feedback profile. Good luck in your decision
