compound slide miter saw/ sawsall

[grumpyvette]

I'm in the market for a 12" or 14" metal cutting miter saw, to cut 3"-4"-6" wide and 3-4" deep rectangular aluminum tubing and channel up to 1/2" thick on the walls,most of the ones I'm looking at don,t come with what looks like a QUALITY blade that's likely to last awhile, or finely adjustable angles or with the 1400rpm cut speed required ,under light to medium use, conditions, so Id like any input on what to look for in a decent blade, saw or related info.
pros/cons?

IM having a problem finding one because a metal saw cuts at about 1400rpm while most miter saws cut at 2500rpm-3500rpm which is way to fast for metal, and finding a finely adjustable metal cutting miter saw that can cut at 5 degrees, or 7.5 degrees as an example seems to be rather difficult

this looks good? but it also looks like its designed for cutting wood mostly

now theres several dozen designs Ive seen without even looking very hard but after talking to several people ID suggest NOT buying a HF versions and sticking to the more expensive name brands, be sure to ask questions about clearances, capacity and parts availability and warranty's
but I can't think of many auto related jobs that a compound slide miter saw, SAWSALL or a PLAZMA cutter can,t do
