Hi, sorry for the late answer, busy period.
What type of BGAs you rework?
Don't have that station, but I know it's a pretty poor performer.
Wouldn't go for it.
Might be usable on small pcbs, but even then...
Will be very hard to do larger pcbs and bgas.
For larger boards, surely with much copper planes a large preheater is very important.
On a larger station you can also do small part.
Give some more info and pictures maybe?
Using IR myself for years now with good success. Nothing H(ot) A(ir) can do my IR can't either.
But surely look at H(ot) A(ir) too.
It has better controllabilty, many prefer it.
