Koni shocks?

[Rampicatore]

Hi !
I want to replace the shocks of my BMW 2000 1969 .
It seems like Koni has a set of custom made shocks for this type of car in it's classic range. Since I'm on a limited budget I would like to have an idea of what it would cost . So my questions is : "has anybody any idea of what the price could be of those shocks ? "
Are there other manufacturers who produce suitable shocks for the BMW 2000 (1964-1972 => E10 series) ?

Thanks in advance !
