Anyone familiar with kids bikes? Is this a good deal?

Hello,
We are teaching my 6 year old son to ride a bike. He is currently learning on an bike with 18 inch wheels but it's obviously too small for him. We have a folding bike that my daughter outgrew but it's a bit too big for him.

Therefore, since this will be his first bike and we don't care if he beats it up, we were going to buy him a bike from craigslist. I found one today in my area for $60 but I'm not sure if this is a decent deal. I know that I can get a cheaper bike elsewhere but this one caught my eye because its a brand I often see on these forums. This bike is a single speed with hand brakes and coaster brakes. What do you think?

Here is the listing:

Specialized Boys Hot Rock - $60
In great riding condition, minor rust and a few small scratches, but similar bikes 200+ new. 20 inch wheels. Hand and foot brakes good, tires too. Just needs hand grips. Great first or second bike- no training wheels. Good for up to 9-10 yr old depending on size.
