And you want the measurements of the base rectangle when it is closer to the tip. Well that was confusing. I dont know how to tell that better. I dont have the english words for that. --- --- http://backloggery.com/a5modeu5/sig.gif <cite>A5modeu5 posted [p:891787993] in Is there a...

Damn, way out of my price range. I suppose I could settle for a 50 inch. <cite>Ic3Bullet posted [p:891790845] in Is there a...
