I would like start with .NET Micro Framework as my hobby project.
What hardware devices would you recommend for that?
Is there something like list of all hardware with support .NET Micro Framework?
Please check following overviews:

Production Modules Comparison Table
I personally like the Thaoe-II and ChipworX most, for old .NET MF version I was really happy with the Digi ConnectME.
