Writing set-up

Hello! New here... I'm wanting to start writing (poetry, stories, etc.) and I need a good set-up to use both in my library and on location. I've looked at the Freewrite and I don't think that fits my budget, plus some of the reviews have me leary. That said, I'm looking for an alternative e-ink set-up with a keyboard and a device such as one of the Boox (have no idea which one to use...). Basically this would be my drafting device then would later transfer to my computer where I have Scrivener to use to edit. Thanks in advance for your help!
