So, any good sites for recumbent accessories? including bags, computers, lights etc. Who has best selection/quality items?

Also, which brands of bags/computers/lights etc are the best quality?

I have found the following to be helpful:

www.hostelshoppe.com
www.calhouncycle.com

As far as quality I only have a half a year and 4000 miles experience on a bent so I feel a little unqualified to comment on quality. I have been pretty happy with the Bacchetta bags though.

One of these (http://www.cateye.com/uk/products/viewProduct.php?modelId=45&catId=7&subCatId=4) mounted high up works for me!
