It is looking like I finally have my Roland organ sold and will now be able to purchase a Rodgers organ. However, I have been to this point in a sale only to be disappointed. Here's the question that I am hoping the group can help answer. There are two Rodgers 835 (two manual drawknob) PDI organs for sale on the Web. One is a new organ still with a former Rodgers dealer. The other has been in a gentlemen's home for 4 years. I am trying to determine which way to go. For about the same price as either of these 835 PDI organs, I could get a new Insignia 577 Drawknob organ with a much smaller specifications than the 835. Or for a little more money, I could get a Trillium 700 series organ that has a smaller specifications than the 835. What is the big difference between PDI and the Trillium? Is it worth the difference in price? Thanks in advance for your input John
