Thank you Barry ,
I love Sandy King Works very much and I googled it after you recomended and Bostick Sullivan sells total 1 liter two part Pyro HD developer for 26 dollars. It makes 50 liter developer and if my tank is 400 cc , it develops 110 rolls 6x6. It costs 60 cents per roll with shipping. If I buy a scanner , 110 rolls development and scan costs me 100 dollars. If I order it here , it costs nearly 800 dollars in Istanbul.
