Don't pay over $40 for a banana pup (even $30 is high), don't buy 2 of the same cultivar unless you know you only want lots of that cultivar, after one year you will be swimming in pups.
Lotta Blue Java (ice cream) bananas are not labeled correctly so make sure the person selling it has fruited their blue java and has identified it. Many varieties of bananas are not labeled correctly from the grower (according to people at bananas.org). For mysore subgroup, Pisang Ceylon seems to be what a lot of people on bananas.org are growing, it's an "improved mysore". Not sure about pitogo, I've haven't heard of anybody growing that in CA.
Also, some cultivars like blue java require propping/support when it flowers. Without support the stem will snap.
