I've been looking at used Speedy's on eBay and I'm torn between being able to tell what a "good deal" is or if the price is so close to the retail that I might as well buy new. What's the cut-off price? Any suggestions? Also does anyone have a Speedy 35? How do you like the size? I love big bags and already own a Speedy 30 of the multicolor bag but I'm curious as to how big the 35 is. The LV store in my city is currently sold out.
