Because HF is just a importer, not a manufacturer the quality is all over the map. And some units are incredible (how can they make this for this price?) and others you'll be lucky to do one job.
30yrs ago I needed metal cutting saw and there was little choice as it was literally 1/8 the price of like a Craftsman or other name brands. But it being a cast iron frame was the main thing for me. You can always rebuild or modify a good frame and I have many modded HF machines. The one that gets most used now is an old HF 14" vertical bandsaw that I converted wood to metal by putting a reduction drive on it. Handier than a shirt pocket and bulletproof.
One of the other shockingly good HF tools is their top of the line Multitool's. I think I got it on special for $35! I was VERY skeptical how good or useful it was, but I bought one for my dad and he loved it. So I tried it out and I can't believe I've gotten along without for all theses years. Of course the blades that come with it are junk, but Bosch blades fit and they rock. There are just so many things you can do with it that no other tool will do. Recently we put in new flooring and I needed to undercut the door frames to put flooring under, no problem with the right blade it will go right through framing nails. Had to undercut the brick fireplace, different blade, no problem. Scrape up ancient linoleum off cement. Wouldn't say no problem, but the contractor was using his Bosch and I my HF and it took us a couple hours and the HF didn't die and did just as good a job.
I've gotten to rely on the reviews on the HF's website. Of course there is always some clinker, a guy who either got a lemon or doesn't know what he's doing. But overall you can get a feel for what you can expect. It was that way with my tile saw. The two top of the line had several probs, but the middle one had good reviews and was cheaper. But in typical HF fashion there was a goof. For whatever reason they thought it was a good idea to put the water feed on the top of the guard. Well it spun the water off before it got to the tile and the blade was cutting dry throwing dust all over. No Bueno por nada. So I noticed there was a flat in the guard right above the front of the blade. So I drilled and tapped the guard and put a 90deg brass fitting on there and stuck the water outlet hose on there and voila! No more dust, cuts like a knife thru butter. I used to cut my front walk 2" thick pavers no problem, then a year later to tile our vanity in the bathroom.
Moral of the story is don't expect perfection, do your homework(check the reviews) and be glad you didn't have to make the thing from scratch
