How much space do the spacers add? I don't see them on the websiteI'm going to have a sale this Saturday ("Small Business Saturday") on the S401. I plan on giving $20 off shipping with a coupon code. This means free shipping to the lower 48 states. I also will be updating my European shipping rates as I'm losing a ton of money on those units. Currently most of Europe is $35 shipping but I will be increasing that on Wednesday before the discounted shipping. It costs me just over $100 to ship a single case to Europe so consider from now until Wednesday a sale for European shipping.
Edit: Also, I have the spacers made but don't especially like the way they fit. Given the complexities surrounding making and shipping them I'm going to abandon this accessory for now. I have 5 sets in great shape I'm willing to sell for $10 + shipping each. If you would like a set contact me via e-mail or start a conversation with me here.
