Found a Leica S1 on eBay for extremely cheap? - leica r

I have a Leica S1 on eBay for $ 450 Buy It Now. Almost everyone in my class photos Leica R system. What do you think of Leica? I want the S1? I searched Google and it looks super weird because it was a prototype. S1 is better than a Nikon D70?
