Indeed....theres been a HZ brochure on ebay that hasnt sold for months. I got extremely lucky with the HQ brochure when it was offered for sale here on the forums. Its in amazing condition. HJ & HX brochures are tough to find and only pop up occasionally......HQ brochures almost never show up.
Now price wise, theyre all ridiculous......how can a sheet of A3 paper be worth in excess of $100? Just paid $115 for a HJ sandy brochure.....theyre only worth what someone is willing to pay....and even then, its not justified. A VU Mambo Sandman brochure can be bought for $30...and a HZ Sandy brochure can be bought for just a little more than that at any given time...thus, dime a dozen
