I suggest Namecheap, namesilo.
nothing other that I know is that cheap.

Agreed.  They're my goto Registrars for cheap domains too.  There may be cheaper ones, but for me namecheap and namesilo have good prices in average with a really efficient dashboard for managing the domains.  I also like Namecheap as with my VPSs I can create two name servers from one IP for my domains.  DNS propagates almost immediately.  With Namecheap I never feel surprised by their renewal rates, like they seem reasonable to what is expected.

If you're unsure @chanalku91 I'd get a temporary domain from freenom just to experiment with the different names and to see which one you feel the most comfortable with.  Once you like a name then check around for best prices.
