Us Toronto area K folks had a little meet-up on Wednesday (hey Diesel, send Ed your email address!). I'd been thinking about maybe upgrading my integral cases from Type 1 to Type 3 and seeing another bike with the roomier Type 3 cases clinched it - I wanted to see if I could get them. It's funny, they really don't look much bigger, but the small engineering changes made by BMW sure increased the useful internal volume.
So yesterday I checked ebay which was discouraging, but then I searched a bit more and found a set on Kijiji for only $200, listed only a week ago.
Then I realized the the fellow selling the bags was in Toronto! Even better that meant the price was in Canadian funnymoney rather than USD.
I messaged him and he replied that he still had the cases. I went to see them today. They were somewhat scrapey, as someone has clearly gone down on them, and the outer clamshell on the lower front right corner had a big sloppy epoxy repair job from where that corner has cracked on impact and separated from the front cosmetic rubber mount, but they were still sound and serviceable (I can always re-do the repair myself if need be, or worst case, pick up a replacement right-hand clamshell cover). Talked him down to $160.
So in two days I went from vaguely wanting something that I figured I wouldn't be able to get, to snapping up a dirt cheap set that turned out to practically be in my own backyard.

EDIT: By the way, does anyone know what the actual difference is between the cases in terms of volume? The parts list on RealOEM lists the Type 3s as 35 Litres, but I can't find anything for the Type 1 or Type 2.
