Should I put any money into my 401K if my immediate goal is to buy a home?

Suze Orman says no, since I'm not getting a company match. Still, I like the idea of socking away money and reducing my taxable income. I also maxxed out a roth ira. So should I save 10-20% in the 401k or completely discontinue it and use the extra income in a 5% savings account for the downpayment? I have about 30 some years until retirement.
