ducky is a respected mechanical keyboard brand.
the zero lineup just happens to be their "budget" or low level brand.
this particular one doesnt have a backlight but does have blue mx switches for only $86

another low cost solution are unicomp classics which use the old school buckling spring type keyswitches. personally i feel they are superior to cherry switches though they are louder.
the unicomp (well its originally an ibm design) features a drip tray which can protect against minor spills. any cherry mx design funnels any liquid right into the switches which sucks. i've had my wasd keyboard die in this manner. really poor design if you ask me.
the ducky will work fine for you however do NOT have any drinks near it at all. not even on the same table. i would also suggest not eating around it as well but that is not as critical.
