My advice would be the same as Barry's.....start saving up.
An original is an investment piece, they are expensive but they hold their value very well.
A copy will always be just that, the manufacture and materials used are inferior and in my opinion you may as well throw your money down the drain.
We have an original ( half was paid for with our wedding vouchers so we were very fortunate!! ) and it really is the most stunning piece of design and very comfortable.
I had lusted after one for years and now I can't actually believe we have one, I often just sit and stare at it.....
