This is by far the best oscar and when you find it get me one:laugh:No really look for something you like the look of, dont rush into it and be propared to go home without one if you dont like the look,or if they look sick,find one thats lively and moves toward you and not hides, if you are un sure go home and go back another day. what you buy will be with you many yrs hopefuly:unsure:
