It's all in what you want. $80-$1500...take your pick. Suspension tech is so much better now than it was even 5yrs ago. A Tora is a great fork. I had one. I'd ride one any day. I try to get the best I can with the money I have though.
Yup, well if you still want cheap, look for RST or Suntour. But I wont recommend both of those brand, you should look for RockShox. Their low-end forks is okay, much better then SR or RST.
