Wish I would have seen this before I left the house, I could have brought a couple to the meeting for you to try...
IIRC I have both the Yaesu speaker as well as one of the cheapies off ebay, maybe even another. I can tell you that you get what you pay for on the cheapy ebay one.
If you're ever down south, or don't mind waiting till the April meeting, you're welcome to try them out to give you some ideas on what you want. IIRC the Yaesu manual tells you (in the back) what the specs of the speaker need to be.
