I like both colordmd and smartdmd I think colorDMD provides a great product where as smartDMD is that at a lower-cost and more open source. If you were to buy all of the components in the kit on either System you would be just under $300 not to mention the work that it took to make the program that runs it. to me having the ability to put it in any machine and colorize it how I want or if it's a game may have already done tweak it how I want has me leaning towards a smartDMD. Also that paired with the fact of it being $100 less is the way to go. I have used a DMD extender in my demolition Man and bought all the components their asking price of $300 is not far off of the cost of the parts if they charge $30 for their labor of colorizing a game that also is well worth it just in time alone. I think PMD is doing a great service to the Pinball community by offering this option for anyone's machine keep up the good work guys I will be getting one or two of them soon I have Spiderman and Metallica LE so also smartDMD is the obvious choice LOL
