Overall, it is considerably different.The manufacturing process for the BJ chips can't be too much different than what it is for the slugged plastic China made chips, right?
The raw materials are higher quality (Chinese firms often use recycled plastics (and/or whatever is handy), the equipment and dies are made to closer tolerances, and high-end plastic chips undergo additional post-injection finishing steps (machining, polishing, etc.) ensuring a dimensionally uniform and quality product.
All of those add significant costs to the plastic chips produced by Bud Jones, B&G, Matsui, and Abbiati -- all of which sell for 10-20x more than inexpensive Chinese made chips.
BJ v7 prices were roughly twice that of Paulson THC chips roughly three years ago, the last time I saw an invoice from GPI.
