Think about it, Where do you go from here. A nice DA-100 is good for what you are going to use it for now, and if you decide to step up a notch, your ready to rock and roll. Besides, you get what you pay for. Not saying that the others aren't good engines, but just try to get your hands on a used DA and you'll be looking for a long time. Good luck, there is no way to get the power when you need it, if you don't have to start. Take care, Bob.
