I am having a replacement bag made using my original R40 bag as a template. Here is the contact information for the vendor: (they have a web site)
Go West Designs, LLC
5560 E. Speedway Bl. Tucson, Arizona520.982.1335 (text ok)
If enough people want one, we may be able to negotiate a better price.
Let me know if you are interested.
Thanks,
Steven
