Based on what I've seen so far in my travels and reading the pron threads, I can break all of the BCC cash sets I've seen into the following categories:
Like/Love Them But Unattainable and/or too expensive, grail sets basically:
Capital Room
Riverboats
Suicide King Club (PM me if you have these, seriously)
Inplays
Grand Cardroom
Like/Love Them and Attainable and Affordable:
Protege
Mardi Gras Small inlays
CDI (I have a THC cash set already, these are disqualified)
Martini Club
Don't Like Them but unattainable and/or unaffordable anyway:
C U Next Tuesday
Samurai Palace (sorry that I'm not sorry)
Nevada Jacks
Don't like them but attainable and affordable:
Mardi Gras large inlays
Desert Palms? (sorry that I'm not sorry again, but are these difficult to locate? I can't nail that down)
Garden City
Fan of Cards
I think the MGK and Cigar and Snifter Molded sets are the winners here, outside of the Web molded Riverboats. PM me if you have anything!
