I think everyone should own a ultralok set,! This set is pretty convenient for small jobs, because you don't have to carry around a huge case to every job. It fits allot of bits from My 200 bit set, so if you need to take additional pieces from your bigger set, or swap any pieces in the Makita set with other bits, it comes very handy, both for your drill, and for you,. Buy it and see for your self!
