I agree, but someone *did* get to enjoy it. I enjoyed it a great deal, as did those who followed this worklog, or so I'd like to think. In fact, I enjoyed it well enough not to want to finish it anything less than all the way. All the time and money weren't wasted if the time was enjoyed and things were learned along the way.
You'll see elements of this case in the next one, and the next one will go a lot more smoothly (and hopefully get finished) for what I learned on this one. Yes, it's a shame it won't see completion, but I don't regret the doing for a minute.
For a direct answer to your question, if I had to guess (and that's all it would be), I'd have to say to finish it right would take at least another 50 hours of work and another $200-$300. Unfortunately, by the time I have either of those available to me, the design will have changed in my head yet again. No, this one was a lot of fun but I need to stop where I'm at.
