The Instant Family...

 and this is just the Instant cameras!

My former (and I do say former) Leica collection of M, Q and SL models were even more massive at one time.

The TOP 5
of the Instant Collection

The favorite is....

The Polaroid Alpha 1 Mint SLR670-X Ming Edition iType 

(That's one hell of a name)

The runner up...
Mint TL70+
(Twin Lens, Instax Square, Fully Manual)

Followed by...
The Polaroid SLR 690
(Considered by some as the holy grail of SX-70's) 

Mint RF70
(The best Instax Wide Camera, Fully Manual)
It has the limitations of a Rangefinder Camera of a close focus of 2.5-3.5 ft

Polaroid i2
(Modern Version of the OneStep with full manual or automatic controls)
Capable, modern, new but something about it missing a "soul" that the SX-70 has.

and for the one left behind....

The Kodak EK6

The camera that caused the monumental lawsuit that took years and essentially damaged both companies.

This was Kodak's middle finger response to Polaroid saying they could care less about those patents.

The one thing about the Kodak is that they did develop the wide format film and with a satin finish versus the glossy finish of Polaroid.

Too bad they couldn't have co-existed.

The outcome would have been so different.
