Ok... I have a dumb question about the speedys: I'm not a huge LV collector (to be honest I only have the black leather Koala bracelet which I LOVE LOVE LOVE but I don't have any bags. I get turned off by the fact that so many of them are faked, even if I know I shouldn't!). But my mom would like a speedy and I've seen a number of them for sale (authorized resellers, my poupette recommended only, even if I hear that she's kindof a pain). I was thinking of getting her one for mothers day (probably too late for valentines). I don't understand the real difference between the numbers after them (25, 30, 35). I bet that it's a size thing, but which do you recommend? I saw a bunch for really low prices at 2nd-handbag.com if anyone's familiar with that seller. Any advice would be helpful, thanks in advance!
