Thank you all for advices. First I must tell you that my financies are not good. my monthly income is about 450-500 EURO, and not allways. I am waiting for example my sallary for february now...

Second, new or secondhand equipment is no option(or very hard) in my country(too small market, not too many photographers), and I am forced to buy 90% of my needs abroad. And that includes not possibility to try before buying, higher bank, custom and tax coosts, and of course shipping and handling costs. Thats why I must ask and get "right" answer before deciding to buy something. And if buy something I need to be as more as I can shure that I get good thing, I don't have enough money to make mistake, because I for example have no way to sell LF camera here, as no one is interested to have one. Only "fool" like me ar maybe one or two enthusiasists.

In any case thank you all for replies
