Looking for some advice from someone informed - I'm not, hence the ask for help. I don't know the first place to start and the LBSs in my area really don't offer much in the way of modifications. They sell lots of road bikes and if you're not buying one, you get very limited assistance.

I have a '09 Gary Fisher Kaitai hybrid, 21" with 700c 28mm slicks (and disc brakes). I want to remove the suspension fork and replace it with a rigid fork. I'm trying to determine what rigid fork I can buy online and bring to my LBS for installation. Any assistance you can offer would be greatly appreciated.

Given my ineptness on the topic, I would gladly paypal some $$ to anyone who's willing to spend a little time advising me on what to buy. I'd like to spend less then $150 on the fork. The goal of this exercise is to make my hybrid as road bike-like as possible. I want to ride more frequently for a few months and if I do, consider going to a road bike next. Thanks for taking the time to read this.
