nieman have distributors all over the states,first i would contact him and see what he can offer using your information then he can give you a product code and distributor to talk to
price will depend on whether you decide to go for cga only or multisync monitor
also very important that you mention the tube numbers/chassis number(yte is the make) and that you mention the tube shape(curved/semi flat-i dunno i can't see from your photo)
