HF and NT both have ~24" versions that have held up well in my use, and I don't think twice about using a $15 breaker for anything I can.
I have a Proto 3/4 I got as a freebie a couple of years ago. It's pretty good, but no way I would spend the bucks on one new.
A breaker bar isn't exactly like a jack, although I understand your looking for something that will hold up.
I've put a 4' cheater on the NT breaker and jumped on it like a ballerina. I was trying to break some rusted caliper bolts on a 82 Ford truck that were solidly frozen. The VIM hex socket bit, the NT breaker and a 4 ft cheater was all it took to finally break it loose after a couple of minutes of jumping on it.
No air was available, I didn't happen to have any PB Blaster on hand where this truck was and didn't have the time even if it was.
Socket bit, breaker and cheater pipe still in 100% condition.
Best $14 and change (on sale) I've ever spent on a tool I don't hesitate to beat on.
