I also really like it! I'm agog to know what the younger Bingley does next. James and Lizzy seem pretty well sorted, so now it remains to be seen what happens with Jane and her Bingley. (And I'm getting a huge kick out of picturing Mrs. Bennet talking of Mrs. Bingley and Mrs. Bingley with great pride).
Will Elizabeth (or any of her family) be concerned that she is taking a step down socially be marrying a merchant rather than a gentleman? I get the financial realities of her situation, and why Capt. Bingley is a good match in many ways (plus, I like him!), but the fact remains that she would move from being a gentleman's daughter to a tradesman's wife.
