Kevin, I'll ask here rather than Email you, as it might be beneficial to others and you seem to be on top of answering here:
When you do the Space Invaders playfield, will you offer the option for me to ship you my stripped playfield to sand and rescreen? I would be totally OK with the disclaimer that it may not be as perfect as a 'new' one, faded inserts, etc.. I doubt I'd spend the $ on a new one, but could really justify the reduced cost of having my old rescreened. Thanks for your time.
