Well, you never know. If the right deal shows up at the right time...I am not ruling out trading completely. Just for me at this time it is wiser to go with what I have and the techniques I will learn can be applied to any camera, so it's all good.
I don't travel, so weight is a non issue. I've never been overseas and I highly doubt I will in the foreseeable future. However, I do agree on the right strap and bag. I like my Black Rapid Sport, but the jury is still out on the bag. Haven't found one that I really like yet.
