I've seen the Chinese brand TACKLIFE show up on Amazon a lot. Very inexpensive and decent reviews. I'm looking at their 10" miter saw. Then I see the Bosch one for 3x the price. What does that get you?
I've owned a cheap one, it failed, bought a festool one, its still square, doesn't fail and the cut quality is great. You don't need to buy a Kapex (the festool miter saw), but something like the bosch, milwaukee, dewalt or makita will survive way longer.
I've bought too many cheap tools to do that ever again.
I also make furniture and do finish carpentry (DIY, not for sale), and that miter saw can only be used for rough cutoffs in such work. I have to do all final cuts on the table saw with a sled or a miter jig. So in truth, the miter saw is 90% useless for that work, because even awkward rough cuts on long stock can be done very quickly with a hand saw - just a basic Japanese-style pull saw that costs about $20.
Some of the Tacklife saws that are about $200 are sliders as well as compound miter. I'm skeptical that you can do anything more than rough carpentry on such a machine, because the slide mechanism introduces even more play. Of course, I haven't used the saw.
One of the merits of using machines in the shop (as opposed to hand tools) is that a quality machine is repeatable and predictable. You can't allow a 44 degree miter or a cut that's 1/16th too short in finish carpentry, so you can't use a mediocre miter saw.
The reason you can't ever be making 44 degree miters is that you may have already milled that piece to final dimensions in width and height, and a mistaken cut will require repeating all that work. In fact, such a mistake might not be recoverable if you were trying to achieve a grain match in un-painted work.
Many of the above factors are not relevant if you really just want to do basic framing!
If you have ever built a picture frame that you intend to hang on a wall and have people look at, you will know how hard it is to get good miters off a "just ok" miter saw.
Still works fine. I think it cost $100.
Of course, it's a bit silly to say that, because you won the lottery, everyone else will. But that always happens, too.
