So the pricing for www.colordmd.com is $399 USA plus shipping.

At our lousy Aussie dollar and conversion rate, it's going to cost a bare minimum of $500 Aussie plus delivery which I am guessing will be at least another $100 to $150 with insurance etc etc.

At roughly $600 to $650 (or perhaps more) it's not a cheap exercise.
The only way to make it more affordable would be to sell the original Stern display perhaps if someone wanted to buy a red one instead of keeping the Stern orange one from earlier models.

I have seen a Fishtales with the color DMD and the colours really work well with the Playfield and cabinet colours of the Fishtales. Star Trek Next Gen also looks amazing. Definately the ultimate mod if u are prepared to spend the money.
