>>3057961>asks for a Polaroid camera>posts InstaxThe mini8 is decent, but it prints tiny pictures and is more for taking selfies with your girlfriends to post on Instagram than any actual objects or scenery.
The Instax 210 is okay too, but the wide format is weirdly proportioned. Other than that, it's not bad. Cheap film, instant development, easy to use though very ergonomically awkward.
If you're talking about Polaroids only, yes, you can probably buy a used camera from the 600 series for less than $100. You do NOT need to buy a refurbished one from Mint or Impossible Project. You still do, however, have to buy their incredibly expensive, non-instant film.
If you're willing to pay a little more, the folding SX-70 is the holy grail, IMO. But that, too, will require you to buy Impossible film at $24 per 8 pictures, as well as separate flash attachments( either disposable flashbars or rechargeable electronic one)
