Query: clogged nozzles again & again - this will be my last epson

this is the 3rd epson model i've purchased. the first one lasted about a year, the second one 1.5 years, and this latest one, the stylus C86 lasted a few months. i give kudos to epson customer service. they are truly helpful and sent me a replacement right away. unfortunately, the replacement turned out to be a lemon. after a few weeks, the yellow print head got clogged. i did 4 consecutive head cleanings, changed the ink cartridge, still no yellow ink. i called epson again. i wanted a refund but it seems they don't do that over there. they are going to overnight me a new C86. maybe it's just my bad luck that i keep getting the lemons. like i said, great customer service, but poor product.
