For what car, what size and what do you want out of it?
Those seem alright prices for what your getting depending on what size you have.
You said in another thread you might be driving on snow, so the SP Sport 600 wouldn't be a good choice as its a summer tyre, and the blocky tread pattern wouldn't grip very well.
The Sport Maxx RT could be pretty good given its the factory fit on the 2015ish WRX STi.
I went with Continental MaxContact 6 for mine and very happy so far. Managed to get a set down from 1100 to 800 after battling 4 different shops against each other. So far they seem quite good.
