Tempted to get a SwissMicros 15.

How does the SwissMicros 15 compare in speed with the LE in solve and integration problems?

You can find speed comparisons between HP-15C, HP-15C LE, and DM-15 (and many other calculators) here, here and here.
The DM-15 is much faster than the HP-15C, and much slower than the HP-15C LE.
