I've just bought an 18 month old titan for 25% of the original purchase price. Fantastic company to deal with to take up refurbs and for general advice. Top notch storage as well, but it is expensive to buy new. For me it doesn't make financial sense to buy it new, as it is already overkill for what I need, but I bought it more out of curiousity than anything else.
I think BlueArc will do much better when they bring out a more entry level system for real world use. In the mean time, eyes on Dell. They are doing some fairly agressive pricing right now.
