I guess check Craigslist or other selling sources in your area for something comparable. It's probably worth the effort to sell but probably just barely, though.
They look so similar that my guess is that they were both made by the same compny. Just a guess, Trend ?looks very similar to the craftsman router crafter, they still have a following. in the US I seem them listed for $50-$125 depending on contrition and accessories.
I own a different router lathe, they can be a lot of fun to work with.
