We're a hosting company.

Like most hosting companies we have several hosting plans (products)

These plans have names.

Like everyone else the names we've been using are boring:

basic; standard; professional

I want to change them. I want something new. I want something that's a bit more imaginative, but I've no idea what!!!

Options on the table at present:
metals - silver, gold, platinum
grades - essential, premier, ultimate
arthurian - round table, holy grail (you get the general idea)
chess - pawn, rook, king

I'm open to suggestions. I'm open to anything at this stage!
