Depends on your reasons for wanting Spoon, but the Spoon wheel is basically a Momo Monte Carlo (bar the red stitching and spoon horn push) so if you want it just for the design and feel then the Momo's are likely to be much cheaper.
Alternatively I have a Nardi Twin Line for sale which is a similar design:
I'm selling a brand new spoon sport steering wheel with brand new EK momo hub for £380. Collections only at east London. let me know if your interested.
Spoon Europe sell just the steering wheel for £370.43.
Thx
