Product review (4 stars): A tough choice
I have actually not made my purchase decision yet; but as a Mechanical engineer comparing the two I calculate the LA Mega with internal drum dimensions 11"dia x14"H @1,600RPM vs Panda: 8" dia x14"H @ 3,200RPM.  So Panda delivers 1,145G's vs the LA Mega only delivers 400G's. Which is ~1/3 the G's of Panda!  LA's Plastic construction has significant corrosion advantages in this application over Panda's steel model, and the volume of the LA Mega is $1,330 cubic in, where the Panda is only 703 cubic". So Panda has almost less than half the usable volume of the LA Mega.  As a red blooded American man, I'm torn between usable size vs power!  1year warranty on Panda vs 3 year warranty on LA Mega.  $ delta advertised price at this time is $22.  ymmv.
