Instant Photography

With all the instant photo camera options out there, i decided to post about the ones that i am mulling over purchasing...
It all started with the iPhone app, 'Polarize'. It basically takes any of your iPhone photos and makes them... you guessed it...  polaroid photo-esque. 

Example

Original Photo:

Then... Pow! Instant polaroid photo:



This is a super fun application but left me wanting more... So i did a lil research/investigating and here are the top contenders... Still having a hard time making a decision tho...
Any suggestions from people that may have any of the listed?

The Fujifilm Instax 210

Lastly,

GL30 Instant Digital Camera

Which do you think is best?
