A few minutes late as usual, though I too noticed the discontinued model is the CSO-300N whereas the current model on the Cuisinart site is the CSO-300N1.
Strange that we cannot find the CSO-300N1 on amazon?
Edit: worse, both amazon and Cuisinart interchange/mix up the specifications, images, and model numbers of the CSO-300, the CSO-300N, and the CSO-300N1. If you download the CSO-300N1 manual from the Cuisinart site it turns out to be the manual for the CSO-300.
Hopefully amazon will get the CSO-300N1 back in stock.
