I've been saving up for a Coronado PST and I'm almost ready to purchase one. So, now that Christmas is over they seem to be out of stock all over the web and the price is increasing from $499 to $599 (just my luck). Does anyone know if they have one in stock at the Clark Planetarium? If they do, is it still $499 or has is gone up to $599? Thanks and clear skies, Dale.
