What makes the atlas worth $15 grand? I can make one out of an ATV winch and a gel-cell for $200. The actual parts costs of most products is far less than what we pay, as is the cost to provide our services to our clients. It's in the overhead to produce the product, the research, the product liability insurance, patent costs, etc. etc. etc.
Really, if you're content to keep on like you are, it's all good. I just don't see how someone wouldn't want one; it's like spending $50k on a chipper vs. just stacking it on a $500 trailer. Most of us have chippers, I'd bet, just the same.
FYI, the parts costs of the Wraptor are a whole lot more than $400.
Like any other tool in this trade; you'll either keep up with the technology, or watch the competition pass by you.
