The Hunter is (or was) working on producing an SVX keychain and a scale model (not sure of the scale).
Seraph is (or was) working on a zip-zap micro RC body and some other type of RC body.
John (not sure of his username here) produced a 1:64 scale model a while ago, he sells them on ebay from time to time for around $75 unpainted.
There's also another model made by some Japanese company. If I remember they are 1:24 scale and they fetch about $300 on ebay if they happen to show up.
And then there's the paper SVX model
I had two until my friends decided it would be fun to crush them
