Paul, not saying you're wrong, but only a different perspective. My dad taught me that whenever I bought any tool, it should be the cheapest I could find. The only ones that break will be the ones I use often. When a tool breaks (used it often), THEN go out and buy the absolute best tool that I can afford. His opinion (that I share) was that it doesn't make sense to spend $100.00 for an oil filter wrench if you change your oil twice a year. However, if you're business is oil changes, it is likely money well spent (this was the actual example he used. At the time, I had no clue even what an oil filter wrench was!).
Applied to detailing, I believe this philosophy has worked for me. I started with a VERY cheap polisher. Had I simply wanted to polish my and my wife's cars, I truly believe it would have been sufficient. When I started doing other people's cars, I learned very quickly I needed to improve my tool.
Again, I don't mean to debate, but to offer a different philosophy.
