As with all other things in the world, the cost of these will be increasing starting today. The raw materials I'm using have went up so much, that I can't absorb the price any longer. I've updated the first post as well, but here's the pricing:
Metal ball guide set, consisting of two pieces (large and small). Price $65/set
Wire ball guide set, consisting of 9 pieces. Price $85/set
I will no longer be making this piece, as a suitable replacement is available from Marco:
Eject shield bracket, one piece. Price $NA (no longer in production, unless large batch ordered
Going forward, the ball guide sets will be made in small batches, so I will need at least 3 people ordering to make it justifiable. So please be aware that it may take some time to get your order produced.
