There isnt really no best drift car m8 as its down to personal taste some prefer shaft over belt driven and other vice versus etc
For around that price i would look at
Tamiya TT-01D
Sprint D
Hpi e10
TB-02D
It also depends where your gonna run it too shaft is better for stoney areas than belts i feel.
I think all those listed are 190mm so most shells will fit straight on
Just dont buy a cheap ebay copy drifter as parts will be hard to find and whatever you end up buying it will need upgrades in the end
