These are as good as it gets and is near your budget. Swissgrip is certainly among the best soft grip screwdrivers out there. Sadly seems they do not have the two large sizes in that set. Are you sure you want a screwdriver for those sizes, because you can't really torque such stuff down with one easily?
You can get them individually elsewhere - the PB 8400.27-125 and the PB 8400.30-130. Both actually offer a 10mm hex bolster so you can tighten down with a wrench. There's also a T40 screwdriver.
Sometimes you can find the PB swiss stuff even cheaper. That set would cost me 47€ here in Europe...
I think
this one is also worth considering. Vessel is always quality. They go up to T40 but with no T8.
