There are so many different trailers out there, you can spend from $800 to over $5,000 depending on what you want. Bushtec and Escapade are great trailers, a little on the upper price scale but they are nice. Cyclemate makes a nice trailer that is less expensive.
You might try looking at a used one, if it's the color you need than thats a plus. painting one could cost about $700 if you have some one do it. http://www.google.com/search?source...GGLL_enUS360US360&q=motorcycle+cargo+trailers
Don't buy the chinese import trailers on ebay. Fit and Finish are NOT two words used to describe them. If I were in the market I would buy a used name brand. Also, if you want to truly color match the paint go to USPaint Corp. They are the ones that supplied the paint to Honda to paint your wing to begin with. Takes about a quart, time you add catalyst, reducer, clear expect to spend alittle over $300.00 for the paint.
Thanks for all the advise, I wound up with an "Alumilite". It looks very similar to the "Tote Lite". LED lights, aluminum wheels, even a spare, a heavy duty luggage rack on top and a platform for an ice chest on the front. Pulls like a dream....$2000.
