New Injectors or Get the Old Ones Cleaned?

[Vincent Vega]

Hi guys
I am going to either send my injectors to be cleaned, or replace them. Have any of you had your injectors cleaned by a place such as motorman fuel injection, Injection Masters, or Injector Rehab? Or other similar place?
Did it work out ok, or did you end up wishing you just bought new ones?
Thanks
