I find it easier to think of DP as an artist. He makes what he wants, when he wants and then sells when he wants. Since people like his art, it is in demand, and someone will always be there waiting to buy it. DP owes us nothing as long as he doesn't charge us way ahead of time and makes us wait while he has our money. The only person really getting short changed is DP (and maybe Sandy if she has profit sharing) since he could probably make a lot more money if he had a more reliable supply and distribution chain.
I ordered my Ulty 120 back in early July '03. The wait was frustrating because of the recurring cycle of them saying it was coming in a few weeks, only to be delayed by problems. But I wasn't charged any $$ until they got it in stock early Jan '04. I got the plane within two weeks of being charged, so I can't really complain. It's not the best situation to want something and have to wait, wait, wait... but I didn't have any money invested until it was ready to be shipped.
Sure, we'd love DP to have awesome service on top of an awesome product, but it's not a perfect world. So, unless they charged you and made you wait more than a few weeks, I don't think we can get too upset.
The only real problem it created for me was I bought other planes that I need to build, and my fun money for now is tied up in getting those going, so the premium components I want to buy for the Ultimate will have to wait a while.
Once I get this bird built and in the air, I'll forget about all the frustration of the waiting. I just hope it lasts a long time and I don't have to order a new one anytime soon. I've been thinking about ordering a spare, or at least getting on the list for the next shipment, whenever that is, just in case. I could always sell it later, probably for a little profit...
