My first scope was free, but it didn't work.
My second scope was under $100, for a cheap USB plug in; but it was so slow I was often disappointed.
My third scope is a Rigol DS1052E. This model and other newer models are readily available for under $500.
On the scope listed in your post, the current bid is 41.5 Euro. In my experience, ebay items typically double in bid price in the last hour of the auction, so this might eventually sell for 80 Euro. Add the cost of probes, and I think you will be over your budget. But, if you can stretch your budget to about 200 Euro, there are lots of better scopes on the US, or UK ebay sites.
