Abrasive Saws are Old and Generally Reliable but don't cut particularly well and definitely not Cool to the touch after cutting, for a while, They are inexpensive (lots of options for Abrasive saws) just get one with a lot of POWER, and use GOOD Blades...
Dry Cut Saws (carbide toothed metal cutting chop saws) cut VERY well and VERY Accurately, Cool to the touch immediately... most good ones are not cheap and the blades if worth a **** are not cheap, Lennox makes good Blades, Freud, Oshuln, and Morse all make good blades, they cost from $65-over $150 each, can be re-sharpened by a competent grinder, if you can find one in your area, Life of the blade sort of depends on the operator, Not enough pressure, Ruin the blade, Too Much Pressure, Ruin the blade, use the wrong blade (aluminum vs Ferrous or SS) ruin the blade, Let Co-workers use your saw, ruin the saw, plus the blade etc.
The ironton saw mentioned earlier works, Just... the clamping mechanism and fence are terrible, you can't tighten it enough to maintain the angularity, and you can't tighten the clamp itself tight enough to miter without dragging the material through the clamping setup, adding clamps helps but the fence will move. the blade works fairly well, the replacement blades also work fairly well but the Freud or Morse blades are head and shoulders above... the Ironton Saw is $300 regular price on sale for $234, the MkMorse Metal Devil can be had from Coastal Tool for $449, and the clamping system is AWESOME the Saw has POWER cutting through 2"x1/4" Angle is like cutting through a 2x4 seriously...
the V Blocks shown in this image are "Extra" for $45 or so... yielding even MORE clamping options.
It has a cast base and housing, the clamping mechanism is Iron and very solidly built.

Rigid makes a nice saw... but at a cost, last I looked they were over $700 or so

Dewalt offers a Dry Cut machine but the base is stamped and the clamping feature is meh... cost is about what the Fein or Morse saws run
