Wish List... Advice needed!

I have found another thing to add to my wish list...

But I have a problem...

I can't chose between the two options...

I need your help and advice

Which one is better??

Polaroid 300 Classic Instant Camera

or 

Fujifilm Instax mini 25 or 7S

Can anyone give me advice or their opinions on these cameras?

Does anyone know the pros and cons better the cameras?

Does anyone own one of these?

Any feed back would be great!!
