I voted DA. I have owned a 3W-100 and it ran flawlessly. I currently own 3 DA-150's, and they run flawlessly. I have never run into anyone that had anything bad to say about DA, but have run into quite a few that were less than impressed with 3W for a number of reasons. So, I went wtih DA, and so far have been very happy. Of the few times I needed to deal with DA service (crash or damage related), the turnaround was quick, and in some cases DA didn't charge me for parts/labor even though it was not warranty or a manufacturing related issue, but clearly an abuse issue.
