P.S. I've never seen any financial advisor say to take a Roth IRA, normal IRA, or anything else before a 401k, whether or not the funds are matched. The theory, as I said above, is that it will continue to grow and you won't be taxed on any of it until you take it out at retirement. At that point many people will be taxed at a lower rate.
I've seen some pretty bad advice given here. This is important so take a look at any number of financial sites, quicken, motley fool, vanguard, and see what they say about 401ks. My advice is to take it. But the best advice is to go find some good advice and choose for yourself. I can say that I've always learned to live on what I get out of my paycheck after money is siphoned off to a 401k. My point is that you probably can afford to put some money in a 401k and you probably won't notice that you don't have it in your wallet.
