Pawn shops in the Miami area?

[El Chiguete]

I'm going to Miami next weekend and I would like to know if there are any recomendation on good pawn shops in that area. I'll be visiting my former guitar teacher that works in Sam Ash in the Dolphin Mall and I'm just going to play EVERYTHING that they have there!!! jeje, but anyway if there are other places to check out let me know.

PS:
Any good concert or something else to see while I'm there?
