What would be a good glove for me? Mizuno Finch?

i'm playing softball this year, and I'm a versatile player. I could be outfield, second, short, or first base. I only have a baseball mitt, and I really want/need a softball one. What mitts are good? Is the Mizuno Fastpitch Finch one good? Oh, I'm 13 and I have big hands. I really like Mizuno gloves, but am open to anything. $75 or less. THANKS!(:
