I have a 30" Harbor Freight 3-in-one. You can do angles other than 90's by controlling the depth of the press. Biggest pain for the break is the lack of a support table. Imagine setting a 1" wide piece of stock 2 feet long on a V block and trying to hold it with one hand while cranking a lever with the other. I did a work around with an adjustable stock support (tripod with an adjustable roller).
I ended up buying a Tennsmith 37" stomp shear and a Diacro 24" finger break. Still have the HF machine and use it pretty much as just a slip roll.
They are great for occasion use, but naturally don't perform like a $1800 shear or a $4000 break.
