After talking to the nice folks at Vans tent at Oshkosh 2009, I ordered their engine/prop combo and saved $1000. That was in August 2009. They also had an Oshkosh savings of a few hundred dollars along with the combo savings. I wasn't sure exactly when I would need the engine, but I knew it was coming up and wanted to avoid any price increase that may come in 2010. When I placed the order, I think they said is would take from 60 to 90 days to deliver. My engine arrived on October 27, 2009 - the day after my daughter was born - two exciting deliveries! A busy week to be sure! That was only about 9 weeks. It came on the early end of the expected delivery window.
The 2010 rate increase never came. If I had waited until April 2010 to order my engine/prop combo at Sun-n-fun, I would have save yet another $500! Who could guess!
I did not mount the engine until June 2010, so I could have waited to buy it at Sun 'n Fun but like I said, how would I have guessed it would have been cheaper. Also, I may have had to wait longer than before for delivery and missed my June install date. Even though it sat in the box for eight months [I was busy playing proud new daddy], it was there whenever I was ready to hang it.
So, is a price increase a certainty for 2011? Unless you have some inside information, who knows - a SWAG at best!
Can't wait to see Vans offerings at Sun 'n Fun 2011!
