[QUOTE="Bangler, post: 8657067, member: 675444"] I'm not seeing the new designs if they were posted. I know designing boxes requires time to tune correctly so I'm going to condense everything down to this post for you to make it as easy as possible! At some point, we need a clear way to compensate you for your time and troubles. $200+ seems fair but we can figure that out when its done. Can't remember if I said it, but thank you for taking time to help me with this. I really do appreciate everything that goes into helping an internet stranger. I've spent a good deal of time over the years helping others on many forums so its nice to see there are plenty of people out there still willing to help.
