its cheap, simple and it works...
Here's a nice unit ...That is a good price on the eBay Battery holder. About $0.72 each. Shipping is cheap for sure. PayPal only is a no-go type of payment with my wife however. What was the lag time for delivery from China? Wish maizien took other forms of payment besides PayPal. They had some other items for sale that I could use in my various Electronic projects.
