like Ras says they are usually pretty close........
but the one at FX trader by HiLo is probably your best bet for best rate.......
the one by Bourbon Beach kinda gives the worst rate......
but it really does come down to which is more convenient......
taking a taxi to HiLo from say the beach kinda defeats the purpose for getting the best rate if you figure in the cost of a taxi.....
