As a CIA grad, I have worked and run many commercial kitchens.  The Kucht KFX480 reminds me of the commercial ranges we used.  The burners are powerful, and make it easy to sear and saute. The convection oven works great, and seems to be calibrated correctly!  The 4 year warranty is beyond most other manufacturers, but the range is so well made I doubt you will need it! Don't spend huge money on high end, "exclusive" brand, the Kucht will do the same job.
