There's a reason why the ready-made ones are still cheap!
Probably made from cheaper Chinese steel.
I used box because it was what i had lying around, similar i suspect to why you used angle for your frame. As for the kink in one side, you bent it with a jack, you can straighten it with a jack! Alternatively, get two small blocks of wood and a longer length, make a bridge from them then use a G-Clamp or similar to pull the bent bit straight then weld some reinforcement onto it. Alternatively use some washers each end as shims, use a second piece of angle as the bridge part of the reinforcement, clamp in the middle to pull the bent part "past straight" then weld in the middle. Once cool, knock the shims out and weld all the way along to gain a double reinforced section that should now be straight.
I also need to straighten one side of one of the frames i made from box, my trolley jack bent that too. The bottle jack didn't bend the second frame i made to get that wheel bearing out. I'll use a similar method to what i've described to straighten my "banana box" section.
