I ran a quick Kappa test on it. There was a nice fat spike at key length 25, as somebody else suggested, but an almost perfect correlation at 100. The message is almost certainly a simple polyalphabetic cipher with keylength 100.
I don't want to discourage anybody from trying their cryptanalytic skills against this, but this particular cryptogram has already been decrypted and the plain text posted to sci.crypt a few days back by Jim Gillogly. The message ID is <32D445A4.3DF@mentat.com> The snake oil vendor then came out with another cryptogram using the same algorithm. It is titled `decryption' and the plain text starts with "There are plenty of programs you could buy such as". Mr. Gillogly broke that too.
