What thickness and size material are you cutting, OP? Do you want to be able to cut aluminum and wood as well?
I have been using a Dewalt 12" single bevel miter saw. I bought it for wood work, but needed to cut some steel for fab work. I was afraid to beat up the saw, but it worked quite well. I had used my dad's 10" Cman miter saw from the 90's before that. The Dewalt has been going for 6-8 years now with lots of steel cut with an abrasive blade (I like CGW blades and flap wheels best), a fair amount of aluminum cut with a dedicated non ferrous blade, and of course wood blades when needed. I did remove the plastic insert from the table that sits under the blade. The dust bag chute is melted away. The laser still works great. The fold up dewalt stand (retails for $200) has been great as well.
I never understood why a metal chop saw required moving the work to a 45 degree angle vs. moving a table like you do with a miter saw. The miter saw may have less power, but the CGW blade cuts much better than either type of dewalt blade that lowes sells and it makes 1/4" thick angle doable. 3/16" isn't so hard, and 1/8" steel is a cake walk. The biggest tube I have cut is 3" square, and it was either 3/16" or 1/4". The saw still works great for wood moldings as well.
It is possible that the dewalt saws made now have changed and may not hold up as well, but hopefully this isn't the case. There have been many tools that have gone down hill in the last 10 years. The dewalt drill bits went from German made and great, to Chinese made and not all that, as well. It was my intention to eventually get a dry cut saw, but the miter saw did good enough for occasional use, that I wasn't willing to spend the money and have to store another tool. This wasn't just home use either, as I used to do small fab jobs for work on occasion and I also did wood moldings as well. I would call it heavy home use or light commercial use, as my work was maintenance and repair and tenant improvement of commercial buildings.
