Converting a Traditional IRA to a Roth

[Guest moneymike]

I want to convert my existing Traditional IRA to a Roth. Will I have tax implications? I don't think so, but I want to be sure before I take this step. Another question is, "Should I do this? What's the advantage of staying traditional vs. going Roth?"

Here's background:

$6000.00 in non-deductible contributions over 3 years '98, '99, and '00. Now worth $5,500.00.
