Upload & Sell: Off
I see what you're saying, but for me the $179 is a business expense. So I can purchase a well-made product that will continually and reliably serve my needs for years, or I can forgo the product and give the $179 to Uncle Sam in the form of taxes. I've set up a business structure to empower me, and this is one of the perks.
When you purchase the product, it comes with video tutorials and customer support to ensure correct procedure, further reducing wasted time from trial & error. I need the ability to test my lenses before big jobs to ensure that on the only day I have to get it right - I get it right. I won't always have time to send my lenses in to Canon for calibration and I like having a tool allows me to accurately configure my lenses on the spot. For me, the $179 is peace-of-mind and a drop in the bucket, in terms of the headache and heartache that I will incur if my lenses don't perform for a client. For me, this isn't absurd - it's good business.
