I'm thinking of buying a new luggage trunk off of e-bay. They have a nice VIP trunk for $115.00 plus postage and it supposedly has lights on it that work. You just have to wire it to your bike. The only thing stopping me so far is that I'd then have to buy a luggage rack to put it on. That would cost more than the trunk itself. I'm also trying to figure if it would look really ugly on my bike or not.
The guy took 180 bucks for it and it looks like it will work just fine. It's brand new so I think it was a good deal, although it's difficult to do much comparison shopping with Kappa. Compared to an equivalent Givi box, I almost stole it.
That's one of the advantages of long winters - lots of time to look for deals!
