Thanks for the replies. I'll probably end up going with the windowed R4. For what it's worth they both cost the same here in Canada so cost isn't a consideration. The dust issue really is important for me and the more I look in to it, the Define is looking better and better.
Not so sure about the windowed version. I've perused multiple forums and many of posts from people who got the windowed version say they would have elected to go the unwindowed route because dust tends to really be attracted to the window panel and sticks to it. Just something I read.
