More info what you want to use it for and why the Chinese ones don't fit your need would be give a better idea what might suit you most...
Doing BGA rework myself for think almost 10 years now using an Infrared BGA Rework station, which I really like.
Probably has some disadvantages compared to hot air but also (more for me) advantages, which I really like.
Not saying you should go for IR.
When I got mine, hot air BGA rework stations where hard to find and very expensive.
IR was affordable, fitted my budget so went for it.
Now I got so used to work with it I don't see a reason to change.
Some BGA Rework Stations I like and would consider if I had the budget:

Then there are others like Manncorp, Precision pcb and probably some more selling (re)branded machines.
If you go for one of the above brands, ask a demo with a machine for what you want to use it for. Let them see how it performs/works for your application. Or better, you play with it too
Kee us posted maybe?
