So - your logic is its worth spending whats half of a lot of peoples mortgage payment on a saw set up that you admit will only get used occasionally, and because its a good brand, itll last until someone is too old to use it, and wont cost much if you break down the payments over half a lifetime.. now sell me on what he should buy if he was a professional that was using it everyday to make a living and lets see if you arrive at a different conclusion on what the most pratical choice should be..
I sincerely dont comprehend the idea that the most expensive pro option is a good choice for the guy that will hardly use it, entirely based on the idea cause its what the pros use
OP - just think - you can cut that cost in half in you buy it when youre 10 and use it till your 90.. Im curious, why we dont have a forum full of people using antique tools.. just sayin..
If we follow your logic he should get a wooden miter box and a handsaw because after all, he only uses it occasionally.
Whether you use a tool every day or you use it only occasionally, you want the tool to do the job you need done. He may never need to cut a 2X12 but if he does it would be nice to have a saw that could do it. It is no different than building a garage. Build one that is large enough to do the things you want to do. Building a small garage that may not meet your needs just because it is cheaper is not a good reason to do it that way, at least to my way of thinking it isn't.
How many times has someone you know bought something and then later on they had to buy a better one because the one they bought didn't meet their needs? Personally, I have seen this happen numerous times over the years with friends of mine and in the end more money is spent than if they had just gone ahead and bought the better one to start with.
You can buy whatever you want. As for me, I will get the better one because then I only have to buy it once. I am retired so I don't use my tools a lot. But when I need a tool to do a job, I want the tool to be able to do it. If the opening poster gets a 10" miter saw, he will be limited in what he can do with it. If he never needs to saw anything other than a 2X4 from time to time, then he will have no problem with that saw. But what if he does? What happens if he has a project next month that requires him to cut some larger pieces of wood? It is far better to have more saw than you need than to have less saw than you need.
