I also have a 4 bay frame but by Gary at RowFrame.com. No need to really post pictures, it looks just like all the others you have seen from DRE/AAA/ext. The major differences between his frame and one you would get from DRE is that I believe DRE uses bent tubing on the corners that is then pinned into the frame while Gary uses regular T fittings that are pinned. Also Gary uses non-anodized aluminum compared to the NRS/DRE anodized. I believe he has a section on his website that talks about the difference. Anodized rubs off after a while anyway.
Gary also built me a sweet stern frame seat mount for fishing or for mounting a motor. My entire frame plus delivery was incredibly cheap, I think it was 50%-60% less than I was quoted at the raft shops around CO. Plus he delivered it. Im pretty happy with it.
