Not trying to sound harsh here, but Moog makes incredibly crazy and well built filtering and modulation devices. There aren't any manufacturers I'm aware of that can come close to offering what that Moog MF 105 offers at any price. Your best bet is to save up for the Moog (even though it's very expensive).
Not what you wanted to hear, but if you're asking a question like this on a forum and want a realistic answer, I'm telling you it.
