I have owned a Harper Tote and it is a beautiful bag. They hold their shape quite nicely. I also sold a few Harpers on ebay and they would always get many bids on them and did quite well. A couple of times there were ladies fighting over them in bidding wars! lol! The auctions often went for well over my original asking price! The reason being is because they can be difficult to find any more, and they are very attractive looking bags. .
They come in the East West and North South ( medium or large) versions. I believe the E/W is the larger one. They also have them available as Speechios, which has the pretty silver outlining.
My experiences with Michael Kors bags, between shoppers on ebay, and on this forum, is like night and day. Most of the topics here favor the Saffiano bags such as Hamltons, Selmas and Suttons, etc.. On ebay, they ( saffianos) didn't sell as well as some of my soft leather bags, such as the Harper.
So just because you don't see a lot of hoopla about it here, doesn't mean it's not popular. It is VERY popular actually and many ladies have them and just love them. I liked mine very much as well and always got a lot of compliments on it, but I am a big finatic about having outside pockets on my bags, so I wasn't using it much and ended up selling it. However, the leather was fabulous and it held up VERY well. Hope this helps.
