I haven't played with them myself because, to be honest, I find them a bit on the ugly side. Perhaps less ugly as outdated. That color green is so 80's. I realize this is a silly thing to base a purchase of this magnitude on, but it's also furniture in my current setup.
That said, I've heard terrific things about their products in general. I've seen a couple people recommend them here and on other sites as well, leaving me to believe they're good choices for not super expensive products.
Like anything in this field, my suggestion is to audition them.
