Are there any "good" HP 30b keyboards out there??

[Jim Horn]

Yes, generally the '20b keyboard has been lower rated than the '30b one. Mine may have the advantage of being a very early '20b, having been one handed out at an HHC annual conference by HP when it first came out. My '30b keyboard has also treated me well though I only use it rarely and briefly at that (for financial calculations I still use my '12C).
