I have tried out all of the cases out there for the TREO 300 ( Handsprings, CaseTECH, Belkin and Bellagio). I am staying with the Bellagio one, basically due to:

1.- Leather quality.
2.-Product Finishes
3.- Confort
4.- Price

I think more cases need to be made similar to this one or the CaseTEch maybe with "ballistic " type material and some color variety.
