Think some are using the Watcon one with good results.

Also there is a dude here on the X selling what he calls "surf seals" hood seals bulk type stuff. You'll have to do a search, I dont know his user name right off hand.
I havent used either of these, but have read some good reviews.
I hear ya on the OEM RN hood seal price. I think I paid $114 or something crazy 4 years ago when i bought my last one here in town through the local dealer...
Also, JetManiac I believe has OEM ones for much cheaper. Dont quote me on that though.
