You don't have to look that much whilst typing because the larger keys are hard to miss. If only it had a USB connector so that the results would appear in the Excel spreadsheet that I send to my tax advisor...

You are looking for one of these.

And this even meets your budget criteria (except maybe for shipping to Europe).

An HP calculator for every need.

Though I must admit this one too is not very exciting...
