Thinking of picking up a 303 in detail can someone tell me the advantages of having both machines?

Thanks

If you already own one take that fun factor and multiply it by two!

On the real....

Some people are more productive with more gear and some people are less productive. Try it and see what works for you. Good thing about SPs is you can sell for what you paid if it doesn't work out.

i rock the 404 & 303, very useful. i highly suggest it.
