You're kidding, right? Of course they honor warranties. They wouldn't still be in business if they didn't!
However, I'd be willing to bet that your DSATX isn't dead. If you really want to get it resolved, go right to the source. The designer of the DSATX is a member of these forums. If you PM him, he's very helpful.
When I was having issues with my DSATX, he got me straightened out.
