If you looked at each tool individually you would have a better argument about if that tool is worth it or not. You also have to look at who will be using the tool(s).
If you take the biggest tool people like to bag on, the Kapex, and do an HONEST comparison, that saw IS the best miter saw out there. Is it worth $1500? No. But whatcha gonna do? Other saws can come very very close to the same cut it makes, but are they 47lbs? Can you put them 2 inches away from a wall? Do they have dual lasers? Do you actually use the darn hold down? The Kapex is the first miter saw I really use the hold down.
Also when people say "it's about the system", that is no joke. The system really does save me time and money. For example, I just bought the TS55. I have owned the Makita track saw for years and it is awesome. I see no difference in cut between the Makita and TS55. The Makita also has more power. About 2 amps to be exact. But I have gotten into the Festool "system". The Makita's cord is short and it is unable to be taken off. When I set up my mobile shop, I now only need one cord and one hose with the TS55 and the cord will reach all around my work bench.
So as with any tool or tool manufacturer, do your homework. Find what works best for you. In my experience though, Festool works awesome. I'm saving time, I'm producing clean products, and I'm not breathing all that dust.
WOW..... that was a book eh? ;D
