cheapest quality mouse of the type you want
used it as a backup for like a week when my DeathAdder died and it honestly felt even better in the palm
the sensor is obviously not as good but unless you're some high-ranked CS:GO player you aren't going to notice at all
it is a little annoying that you can't stop the LED breathing but some people might be into that, IDK
