Another possibility. Look around for hamfests and other ham radio related sales (auctions, ads in the paper, monthly meetings). I got my 44 space, all metal rack for $5 at an estate auction for a man that was a ham radio buff. Perhaps I should not reveal this little secret because I have gotten other goodies too. A pair Amperex EL34's NIB and a four channel tube mixer, for example. Sorry, had to brag.
