Should I buy some used Spinergy Wheels?

Someone offered to sell me a pair of Spinergy XAERO Lite road wheels for $300. They reportedly have low milage and have only been riden by a small framed lady. Can anyone tell me if the wheels are worth the price.

Thanks

What year?

and yes you probably should buy them.

Thanks AussieRob. The wheels are three years old but haven't been riden in the last year.

These are also 3 years old, for a far bit less than $300 (at least for now):

Thanks Scotty_Dog. We'll know if they are cheaper in a few hours.
