There are a few Betty Chain bags on Ebay, (picture below). I am interested, but want to know about your experiences with the chain. I have read some negative posts in the archives about the chain, but don't know if the chain itself is heavy/uncomfortable, or the bag, or ????? I have 2 of the Betty Hobos, and they are the lightest and most comfortable bags I own, so I am a little perplexed. I do have a Marc Jacobs with a chain, and it is very heavy and uncomfortable, and, obviously, do not want to get into another bag like that. Also, there seems to be 2 sizes of this bag that I noticed on the threads. The one on Ebay, below, is 15 x 10 x 5. Did this particular bag with the chain come in 2 different sizes, or are these dimensions for the one and only size? I don't like humongous bags, and don't want to look like I am carrying luggage. Thank you!!!!
