I agree with the posters above that making a sideways move is expensive. It's better to save a bit until you can move up. And when you do move up, you should move up big time rather than a nibbly little bit because small upgrades are expensive too. When you do move up, I would suggest you look to the $800-$1000 used price point as the next worthwhile upgrade. (Boy it's fun spending other peoples' money!)
However, having said that, if you want a change and want to do it cheap, one of the best audio bargains is the PSB Alpha. It's cheaper than the model you're looking at and with a sub it would be a great bookshelf monitor until you're ready to move up.
