Someone PM'd me and I figured I'd just answer publicly because I didn't want anyone to get the wrong idea.
Any frustration expressed in this thread is directed 100% at myself...it's not the first time I ran with an idea spending lots of time on it (fortunately this wasn't that much time) and found out there are other options, or just no interest. I get overly excited (because I truly love doing things like this) and start spending time on it without thinking all the way through. It's a bad habit that I can't seem to break. The fact is no one forced me to spend time on this. Someone asked for a solution, and I ran with it. Bottom line is, I think it's great there is already an option out there for a decent price. For the number I would sell, and the time I'd spend making them, it really would be a losing proposition for me for such a cheap part.
Let's hope the SOC gauge doesn't turn into the same thing, because that project I did spend a lot of time...and now money...on. heh
