Alternative to plastic "clogging"spray heads??

ive been searching everywhere and i cant seem to find anyone using something other than the plastic 360 spray heads that im using also.
im looking for something more maintanence free such as like stainless steel sprayers. does this sound practical? any info would be great

Thanks

im using this big blue needle jet sprayers...basically you pull the top off and clean the needle and your good to go...got them from the hydro store, but were like 3.50 a peice, YOUCH!

They have stainless steel sprayers but they actually clog more frequently.
