the bigger the piece, the more the shipping. I know i shipped a double mario sign, (comparable) to CA and it was 35.00 in shipping. I also had a wooden APB seat, that was boxed up, roughly 14" wide, 14" deep, and 14" tall to WA and it was 29.00 Shipping has been the suck lately. While i strive to make every part 100% accurate, the sides i sent with him were off just slightly on one plane. Probably 3/32 too tall on the highest point.
I copied it with a tape measure, and a square. Normally, i'll take a game apart, lay it on it's side and trace it, then use a large T-square to take measurements. Unfortunately, 720 is so heavy, you could be seriously wounded trying to lay it down lol.
I may visit doing parts later this year, i have to concentrate on getting cabs done/games sold at the moment!
