Concider the fact that there has been a sizable reduction in price of new stock since their original introduction about 3 years ago (circa £145-£165 each), apparenntly due to a "glut" of stock being "found", or so I was told.
I sold mine off for a bit more than those being offered at Glendale, six months ago. And this was after the new stock price had dropped, and no price negociation too ! Supply and demand, supply and demand. Good luck.
