Curbside Cycle, http://curbside.on.ca, in Ontario, Canada is selling off their remaining inventory of Mezzo bikes. When I last talked with Aaron at the shop, firstname.lastname@example.org, he had a few Mezzo I4's and a few Mezzo 9 speed bicycles left in stock. They are not listed on his website, but you can call his shop and find out what is left if you are interested. They also might list them on eBay from time to time, so you might want to check there in the future. Aaron was more than fair with the price and I personally had a pleasant time dealing with his business... even at over 1000 miles away in another country.
Just trying to pass along a good deal for someone who might be looking for this specific bike.
