If I recall (not 100% sure), even with the best sale prices on the RS250's, they still went for $399 new plus shipping. So you're getting them at 1/2 off, only slightly used...
Even if I'm wrong and it was $299, you're still getting them much cheaper...and you can't get the 250's for for anywhere near that price right now new.
I'd don't ever remember seeing the Bigfoot for cheaper than the $395 it's going for now.
I'd say the 250's and Bigfoot for $410 shipped is a hell of a deal... bigfoot alone at sale price with shipping would cost more
