[Buying] ESP without extras

[Snof!!]

Hey,
I haven't used hacks for a long long time (must be 8 years ago). At that time I had access to a launcher and could start right away

How does it work nowadays?
> What ESP hack can you recommend me?
> How does HWID work and what do I need in addition?

Glad about detailed answers

If there are Germans among us, you can also write me a PN in German
