You know your machine and how much you use it better than the rest of us so you will have to make that call.
My 2 cents is that if it is $90 I would for sure. If it is about $300 with labor and I expect that it will last at least one month it is cheaper than rent on a new machine but do you NEED a second machine and would you replace it if it wasn't repairable or just live with one machine?
I will get a second BAR 97 when my GEN2 dies but I see plenty of 1996-99 cars.
I've hit rock bottom but I brought a pick and a shovel and I'm ready to dig!
