All depends on how much you want to spend,you can pay good money for tti's,
I agree, I can not afford TTI's so i will go for the Hookers, Later in life i would like TTI's or Dougs. You must ask yourself, How much you want to spend? If you dont want to spend more then $200, well there is alot of choices and they are all about the same. FYI at a recent car show last June, I have the same question, and wanted to see what everyone was using, 80% Hooker 20% TTI. Im sure cost was the reason. After i would see what type, especially non TTI's, I would look uder their car to see if they were all dented up. I would say it was about 60% to 40% (60% being not dented). I was supprised because this is a major concern.
Anyway, i started a thread a while ago named "to header or not to header" and got alot of good info on it. Just look it up in the search if you want.
