Don't go looking for cheap ones, you'll regret it getting banned because of it or only have issues with it.
The usual price for a spoofer that offers to spoof every, or almost every AC is like 30$. I can only speak for Elusion as I've only used it for a couple times and they seem to cover everything.
But to be honest, if you want to have a long-term solution, go for RAID0. If you don't know what that is, google it.
TL;DR: It's basically a spoofer that you can control yourself by combining two (in best case) identical SATA or NVME drives to create such a "RAID0".
For EFT, that'll be enough to keep playing even if you're HWID banned. There are also downsides to it like: If one of the drive fails, all of the data that's on it is gone.
