Old SIGMA Canon Lenses for DSLR - rechip

Hi Folks,
..here we go again. There is this nice Sigma Lens: Sigma 70-210mm F:2.8..
Well it is my wifes, I found it in a garage sale but it throws an error on her Rebel.

Searching the web I found this chap: http://sigmarechip.sim​plesite.com/430608848
he sells a rechip board + instructions for peanuts !!
Having two left hands I contacted him if he would do the job - he did! Great, despite shipping and work which included a
complete revision, an unbeatable price.

Have a look for yourself
