mies reproductions  

after reading a lot of the websites on knock offs I am begining to have a difficult time determing what is a knock off ??? when it comes to a Barcelona or a Bruno chair.
I own 6 Brunos from Knoll from around 1972. I bought 2 from Furniture fancy I had them all recovered to match. I really can not tell what is from knoll and what is from Alphaville the real manafacture who has them made in China on runs of 1000 at a time.
I bought the two new ones cause i wanted 8 chairs at my dinner table I was tired of waiting till some one on ebay sold them for around 600 beat up and a must to redojust caue the chair was knoll the one i got from furniture fancy were real nice , but I changed the leather cause i wanted them all to match.
Now in my office I have 5 barcelona chairs scattered around. In my personal office I have 2 knolls from 1970 with stickers on the bottom and of course standard issued black , bought on ebay for 1200. each 2 years ago. still soft and not cracked. I ended up buying 3 from Furniture fancy for around 600.00 each and they are really good looking . will someone tell me have I commited a cardinal sin. have I taken food from some orphans . have I violated the rules of being a true design addict.
I would like your opion on great reproductions and why Knoll should be so expensive ( remember I have both) I read the discussion on the egg chair I am still amazes that, that chair cost 6000 grand for fabric in Kvadat and 10,000 in leather I have never seen a repo on that one and am wondering if the repo bases are any good and look like Fitz Hansen.
