Dnail buys their shit from China n slaps a sticker on there too, no? Besides making the second plate heat up.
I can also confirm that the products you guys are referring to are fraudulent, doctored images from D-nail originals. Allegedly the individuals responsible for the fraudulent listings are Americans - not Chinese!
Also D-nail buy existing t-shirt presses from China and put in their own controllers for both plates.
They do not retain the Chinese electronics, but rather the mechanical press side of things and the plates are retained (I am unsure about whether they use the original wiring for the one plate which was already heated, but I doubt it. I can speak with the man who designed the modifications to confirm this though next time I am in touch with D-nail people).
Further to this, remember that the price that these presses are offered at really is not a hell of a lot more than the original t-shirt press, I recall the original costing a couple hundred or something anyway
I've also yet to see any other good purpose-made home presses (not to say that there won't be loads of them inevitably cropping up eventually!).
There are some potentially better presses that I have seen available, but these are large commercial presses, designed to press major weight and seriously not products that lend themselves to shipping or personal home use.
At the moment, if you want a purpose built rosin press, d-nail are really it. If you want to jerry-rig, by all means (and who knows, somebody could make a breakthrough in the process!), but don't be surprised if you spend the same kinda money to get the good results as the d-nail press would have got you!
