Ciphertext from Hell

Allright... This thing is starting to piss me off. Any clue what cipher was used to encrypt this? I've been poking at it since Saturday evening and I have very little to show :(

I know two things - it is a substitution cipher but not a ceasar cipher. How do I know? Because I already did a brute force caesar check on it and I got nothing but gibberish. So back to letter frequency dance... I really want to decrypt that crap now!

But it will have to wait a bit. I need to start studying for my exam on Wed...
