Mad Amusements, $139 cheapest brand new Dot Matrix Display on the planet for Aussie buyers, excellent model, less than $45postage and very very easy to pay the man with paypal etc. I always buy from Mad, very quick service/postage. Never had a issue with many orders. Always refunds any over-postage.
*note*, I buy alot of Stuff from Pinball-Life, but they charge Americans $139 for a new DMD, but charge us $149 same product, plus postage.
