Looking to upgrade to an open hole B foot flute. Which models and brands are good?

An option I have is: a used Yamaha 584 HCT or a Gemeindhardt (new) maybe 3SB or AFL31OSBNG with a free picollo?

So, what is a better option?

Any other possible options that might be a good upgrade under the 1800 or so range? Preferably: Open holed, b foot, split e/c# trill.
