If you're a do it yourselfer I think trying your own installation is a good way to go. Squintal's write up is very good, and his diy crown race installer/headset press suggestions have been used by many. The one thing that is hard to do yourself (unless you have some unusual tools in your shed) is face/ream the headtube (if needed, some manufacturers do a good job of prepping the frame, some don't; you might ask IRO). Just be patient and follow instructions as laid out by Squintal (or go to Parktool and review theirs as well, search these forums or roadbikereview.com or mtbr.com for more input). Good luck!
