As you correctly point out, a 10mm will give you higher magnification, but Saturn will move out of view quicker. A 15mm will show saturn slightly smaller but it will stay in your view longer (depending upon the FOV of the eyepiece). Which raises another point. Eyepieces come in varying Field Of View (FOV) types, from around 45degress up to 110 degrees. A Wide Angle (FOV) eyepiece will give you a bit more viewing time.
If I had to recommend an eyepiece that I think would be within your budget (based on our prior involvement), I would suggest

You might see them referred to as 'gold line' eyepieces on other forums.
