I imagine the problem is setting up and maintaining a website. Sure would be nice to comparison shop in your skivvies, at midnite!
I'm not a Husky guy, but my dealer is only a phone call away. There are horror stories about dealers that shy away from stocking parts and servicing their customers on this forum, but I find that I can get about anything I want within a reasonable time. Not as much fun as surfing the web, but I doubt if you'll see anything better before somebody comes up with cheap software that allows a dealer to build and maintain a big website with only an hour or two of free time every month.
Jack's small engines has some stuff, there's a few things at Banta saw up in Canada, don't forget Walker's and Madsen's, and there's a link somewhere here on arbo-site for OPEcenter, which has a lot of husky parts listed and priced...but you'll need a parts list to identify what you need.
Sorry, that's the best I can do, maybe somebody can do better.
