I have some prototypes for sell at reduced prices if anyone is interested. They are not on my website but just pm me and we can figure something out. I have 3 singles that are from my "old" batches. They are all perfect but my newer batches are much better. My quality has GREATLY improved over the last few months and they just don't meet my quality standards anymore. The 3 singles are $25 each and that includes shipping. There is nothing wrong with any of them, they are just rougher then what I sell now. I also have a double that is perfect (meets my current standards) but I spilt acetone on the bottom and didn't see it until it had melted a section of it. You can't see it once installed and it doesn't effect it's function in any way. But it's a flaw and that doesn't cut it for my standards. That one is $40 and includes shipping. You can see pics of the cup holders on my website. The link is in my sig below.
