IRA & 401K - is that too much?

I am regularly investing money in my 401K & I plan to continue doing so. I put 6% of my salary in my 401K & my employer matches 50% of that; so that makes it 9% Well, if I continue doing that till I retire, I will end up with close to $1 million. $1M for just 401K is I think pretty good. If I continue being sincere with my 401K, savings & other investments I think I would amass pretty decent money when I retire. I am not being cocky but I think if I (or for that matter any one) is sincere & regular with his investments he should be pretty rich

Now, the question I have is should I invest in Roth IRA. Isn't 401K investment good enough for retirement? Plus, I don't know if I am going to stay in USA for ever. And, if put so much stuff is in my retirement account, I won't have a ot of money to "play with" right now. Is this okay?

Well, these are tough questions to answer. But I think Roth IRA should be a good investment. With Roth, I can withdraw my investment any time without penalty. And If I have to withdraw the amount, I will lose 10%; I think 10% is something I can afford to risk.

After doing plenty of research I have decided to go with Vanguard for my Roth IRA & invest in Index funds. I plan to buy VFINX first. I plan to buy Small Cap Value Index funds, Total International Stock MArket fund & REIT Index fund in the future. Go Vanguard!
