if someone sells a plug i made on ebay for say, 50 bucks,you must have done something right
look at it this way-
A- my plugs are in demand
B- My plugs are fetching 50 bucks
C- Thats 50 bucks that someone selling beachmasters wont get
D- once word spreads that my plugs are going for 50 bucks, the demand will increase, and you may feel inclined to raise your price.
All well and good for you commercial guys, but there are still some of us, that don't sell.. strictly hobby types.
