Mines $1860 after tax. I'm not sure what good a warranty is on a box, or if it's transferable.
I bought an as-new Classic 78 a few months ago as well. Incidentally, I paid the same $1500, and I also felt I got a good deal. Mine is green, not black. My student-pricing on a new one is just over $2000. Not sure how you managed the $1860.
As far as warranty...I added a home-grown side box / locker to my box. In the process (which required the removal of my drawers), I guess I managed to booger up a slide or two. When I mentioned the slide issue to my student rep, he said "the boxes are warrantied for life...I'll get a slide set out to you". I had also mentioned the issue to our SO truck guy...when he came by the next week, he had a couple of slides, and helped me swap them out. So, I thought the warranty on the box was quite handy.
Having the Classic 78 box, which I really like, I'd LOVE to have a Classic 96. That would be about perfect, IMO. I like the lower "shelf" height of the KRA series, though I also like the idea of an additional "deep" drawer of the KRL series.
I've got my 1/2" sockets standing upright in the top drawer of my Classic 78, in some of the Harbor freight socket trays.
