I've got about $600 of disposable income at the moment. I need some new bibs, and I could get a few pairs of Assos with that. But, I can live without new bibs. What I'm looking into is a set of rollers, the Kreitler Dyno-Lytes. If I get a set of rollers, I'm pretty set on these because of the quality. But.......

Is a set of rollers really worth all of my disposable income? It will be quite some time before I'm in this position again with the opportunity to spend $600. I live in Florida, so it's not like I don't have the opportunity to train outside everyday. But rollers apparently help your control more than anything else you can do. Any thoughts?
