Frigidaire Washer - Affinity Front Load Review

We bought our washer and dryer set in December of 2007.   We have not had any repairs done to our washer.  It cleans clothes great.  However, within the last 8 minutes of the wash it starts to vibrate a lot.  You think an airplane is trying to take off from our laundry room and you definitely can't let anything sit on the machine...it will bounce off.  I did notice a slight odor if I don't leave the door open to air dry.  It also seems to leave little black marks on the clothes.  I wash everything inside out to prevent ruining our clothes.  I was so happy to be investing in Energy Efficient appliances.  Apparently, you need to spend a little more.
