Polaroid camera, first time buying one?

I have a dlsr (nikon d90) and its so heavy, sometimes thats really inconvenient when being with your friends and i really like how instant and vintage polariods are, so i'm looking to buy a polariod camera with the most common film and stuff so its easy to maintain.around 40-50 dollars at the max and its gotta be worth the money. (since i spent it all on my nikon… ) xD
if you have tips for beginners than don't be shy.

I would not buy a Polaroid camera, I have a Kodak Easy Share CD 33 camera with a 4G chip in it.cost $80.00 many years ago at, where else. WalMart. I don't know how the polaroid film is holding up after may years of not being used, don't even know if you can but it anymore. My little camera I can put in my pocket.

Well here's your problem

where do you get film? I know where you can get film.

as you can see, at the cheapest, film is $14 for 8 shots. Its not worth it unless you have an entire paycheck to blow
