Query: AVOID AVOID AVOID

After 40 years my Kitchen-Aid K5 started having problems. The 6 qt bowl looked like a good upgrade from the previous 5 qt bowl.When the machine arrived I was dismayed to see how cheaply made the new bowl is. It also has dreadful ergonomics. The dough hook and flatbeater are NOT dishwasher safe. Do these people ever bake?Shy of two years it quit. Off to the appliance repair man. He groaned when I sat it on the counter and said "not another one of these".He showed me SIX in his work room. Cost was $90 to repair.A side note: the Kitchen-Aid website says it was a two year warranty. When I contacted them I was told "the website is in error". Greatcustomer service.His take: the 5-series machines were amazing - in spite of the one nylon gear. The 6-series machines: JUNK.So proceed with great caution.
