Yeah, I can get a ChromaCast case on Amazon for $55 with free shipping. ABS is only a little more. Financially it's probably close to a wash--at best.
I am not convinced there are Eko collectors. I checked on Reverb and Ebay... You can find cases for sale occasionally, but I haven't seen any that actually sold. Some of the wilder, pristine Ekos guitars go for up to a grand, but most are in the $400 range. I am not sure whether I have ever actually seen a genuine Eko. I think I may have seen a Vox or two made in their factory. I am a little surprised there isn't more enthusiasm for them...but then I have no direct experience with them so what do I know?
I do like the idea of having a unique case. Just not sure how much time and effort I really want to spend on it. That said, I know I have some spray adhesive around here somewhere...
