Not all battery brands will fit two units in the defender battery box... Which leads to my next question that I have always wanted to ask; what other brands than Optima will fit two batteries comfortably in the Defender battery box if you want to run a dual system without using optima batteries?

I got mine for around $350 from this place: http://www.batterysystems.net/

"Worth it" depends on what's important to you. For me, reliability is king and there is no better in my book than Odyssey. Considering that a dead battery could cost me a day or two of a once-a-year vacation, it's well worth the extra $150. After a dead Optima red top and later, a dead yellow top, I made the switch to Odyssey and haven't had a problem since. With my single battery, I have fewer cables, more space in my battery box, and a much cleaner setup that's easy to diagnose. If you are on the Blue Sea fuse panel bandwagon and have one installed in the battery box, you'll also find that you can access your fuses without having to remove the battery.

Any group 34 battery will work. You may need a small packer to get it clear on the bottom.

And you could always put in dual Odysseys if you want. I've been happy with the Exide Orbital marine starting/deep cycles. Many years of hard use.

Going on 4 years with the yellow-top optima's in my truck and no issues...

I will admit that they sit on a battery tender when they are not in use for more than a week or so as winter storage is what killed one of my old Optimas...

As to the single vs. dual...I tend to leave my lights on...so better safe than sorry...

So D34 is a size denomination? You're saying then that the Odyssey and Exide are same size as Optima? I've had a Optima Yellow Top for 6 years and I have mixed feelings about it. If there's something better out there in the same size I'd like to know. I have two new Yelllow tops on the shelf in the garage that were supposed to go into my dual battery system but I'm hesitating. I have a battery box 'shelf' ready to install and I need to be able to fit the ACR and a fuse box as well.

My current Yellow top is 6 years old is not holding a charge very well. If I don't drive it for a while it needs to be on a tender. if I drive it daily its fine.
