I always use JA$$ when I can. I think the RS cruise was $50 US (they gave us a discount) and I think I paid like $6000j? Quality's has his prices in USD, I suppose for the stability, but I have always paid J$ there too. And his prices are still great, $13 for lionfish, $15 for snapper or grouper, and $16 for mahi mahi (so good they named it twice!)
Don't quote me on those prices, they're from memory, and as always subject to change.
