i just went through this exact scenario myself . After asking members here ,i purchased a premium and no regrets at all!
I was lucky enough to get a new in box premium 10 days ago.
The extras on the premium are great! The hammer, rising cross,spinners and extra lighting are a nice upgrade.The hammer itself is just an Awesome feature ! Don’t know why people complain about the hammer so much?
To add my machine build date was oct 8 2018 so I’m assuming this is towards the last of the run? If this helps at all
Good Luck!
