Maybe that's my problem. I'm accustomed to having all the data available and being able to run command line tools in batch mode. If I could have that database of data, I could write the tools, then grep for the result I'm looking for. Now that's what I call a speaker selector! This whole enter the data, interactive GUI thing just isn't my bag. Way too slow.

OK. Its becoming more clear now, although depressingly so. It seems the best defense against lower quality motors is cash. Oh well...
