Budgets are a double-edged sword. They can confine your prospects but also rein you in from unnecessary overspending.
If the price seems fair and just to you and, more importantly, the bike seems to be the perfect fit for you, by all means make that investment. But do make absolutely certain that this is the bike you want\need. Granted $600 isn't $6,000 but money is money no matter how you spend it. And there's no point in spending it twice. If this bike fails to meet your expectations in any way, unless you can sell it to someone else, that's exactly what you may find you have to do to get the bike you originally wanted to begin with and that'll make an additional purchase most unwelcome.
What I recommend doing is Googling ''Trek 1.1 problems'' and see what others have to say negative about the bike (I got 1,900,000 hits). I'd also recommend Googling ''Trek 1.1 reviews'' (I got 10,100,000 hits) and see what both sides, pro and con, have to say. And *always* weigh anything anyone has to say against what you either know, believe or suspect.
Many Trek stores will let you test ride a bike (up to a certain line). Our local Trek store stops those free test rides at the 5-series (I think). Also consider a Specialized bike. To be honest, I wish I'd have looked at the Specialized line before I bought my Trek. I think I could have spent half the money and gotten very close to the same quality bike\ride - maybe or maybe not. It's a moot point now.
The point is, definitely do your homework, ask, ask, ASK around. Bother, harrass and pester bike mechanics, enthusiasts, novices and anyone you can about not only what you are looking to invest in but also what they have, why they like\hate it and what they'd recommend or do differently if they could do it over again. Make a physical list of pros and cons for the contenders and then make your investment. I think you'll find all of that hard work will most assuredly pay off with each seamless pedal stroke.
