Just in case anyone is interested, I bought a BikeMaster TrueGel Battery MG12-BS which is a direct replacement for the original battery, YTX12-BS.
You can buy it from Bike Bandit, but it's a little pricier and does not include shipping.
I bought the battery on eBay on Monday and it arrived today. There are several places selling them for about $86-88 with free shipping. I found a place selling one for $78 plus $10.50 shipping. With the great forecast for this weekend, I didn't want to risk waiting even longer for a free shipped battery, so I bought the $78 one.
Like I said, it arrived today. I measured 12.9 volts on the terminals out the box. It fit in the stock battery holder very nicely. After making all the connections, I smeared a little dielectric grease on the terminals.
The only issue is the black plastic top cover piece. The dimensions of the battery are just a wee bit different, so the cover doesn't sit perfectly flush as on the stock. But it's minor and you really have to look to spot it.
Here's a pic of the battery installed.
While things were apart, I decided to clean & re-oil my Unifilter and clean up the brass battery over. The brass battery cover still looks pretty good, although the darkened areas are lightening up. For example, what is supposed to be the blue field on old glory is no longer dark, so it's harder to make out the stars.
Anyway, put things back together, and rolled her out to fire her up. She started with no problem, good and strong.
Here's a shot of her, after I fired her up.
Afterwards, I installed the compass I got as a Christmas present. It's from Newbonneville.com. Easy installation on the right handlebar. It should complement the clock I have on the left handlebar.
