Brother Sewing Machine - Computerized - CS6000i Review

This Brother CS6000i is a good workhorse... I really enjoy working with it, especially because it is lightweight and can carry it from room to room.. I like the idea of the extra bobbin holder and the needle threader, for the older people that use a machine... the buttons on the machine are easy to understand and the directions are ok..the only negative I can think of is how to oil the machine, and to replace the lightbulb.. there isn't anyting in the manuel for that.. so what can I do to find out those answers???  the machine is easy to change the needles... I change them according to the fabric that I am sewing... the thicker the fabric the bigger the needle.. and I especially like the  length of the stitch..that is most likely the best I have found in many machine...
