Bruce ya hit the nail on the head the seller has no idea what he has got, 100$ for shipping is more than the current bid for the plane and if the plane arrives damaged you pretty much stuck with a broken plane that you may or may not know how to fix.
San Francisco is about 40 miles from Santa Rosa for me it might be a good deal to drive up there and get something like that not like I am interested.
if you have to pay a huge shipping bill to get it half way across the country, get a new one instead that has some backing behind it and a guarantee, for the price the tower is not a bad deal at all, and as I said in my post earlier as with most of the tower/hobico/great planes trainers there is a crash guarantee if you have a instructor present and you crash, they will replace the plane for you, that is hard to beat IMO.
BTW on some of my purchases from tower there has been some problems,product was not as high quality as advertised, arived broken, small stuff, there return policy is top notch some products exchanged and some returned for refund .
