Timothy, I wanted to research that print bed and controller a bit and so I googled "techzonecommunications.com" (the vendor for the Huxley print bed linked above). What I found was a history of them not fulfilling orders and product quality issues. Here is but 1 report: techzonecommunications.com as a seller
Not trying to dissuade you from finding a working hot bed now but I did want to point out what I found.
cheers,
Michael
