I second that, I've had really good service from Chicago harley. You can't beat them. I've ordered three times from them and received shipment within 3 days on 2 of them. The third was on backorder and you can shoot order questions to them on their website forum. Their url is here .
I also ordered a parts manual from my local dealership ($45). Saw one of the mechanics going through it and got them to order me one. It has technical line drawings of all parts and part numbers, also shows how things fit together.
It really fills in the gaps of the service manual and gives you the actual part numbers of stuff like that particular washer, seal or bolt you are looking for.
I don't know how it compares but I just bought the Clymers 02 Road King service manual off of Ebay for $22.50 (new). At that price I thought I would give it a shot before paying $56.00 from the Harley dealer. I've used Clymers before and they worked pretty well for what I do. There is a guy on Ebay that seems to have a ton of various Harley manuals.
