whirlpool gold dishwasher, or kenmore(by whirlpool too)
about 600 dollar.
For me DIY. It is not too difficult , but I don't think if a personal never install a electric plug could do the job.
If you installed your rang hood, and painted your house then you could try install dishwasher. It problem is if you screw up a rang hood, nothing too bad. But if you screw up your dishwasher and there is a water leak, you may have to redo the floor ceiling of you basement...
