I've had an Optima red top last for over 15 years in a car that was used only occasionally and never had battery tender. It was also run completely flat a couple of times while sitting in the car in the garage. I'm convinced that this is the most robust commonly available battery on the market today. The extra cost of an Optima is well worth the peace of mind for me.

There are a few online retailers that sell these batteries, including ebay. Just shop around for the best price (with shipping). The problem you're going to have is that the yellow top does not come with reversed poles like the red top, so you will not have enough cable length to reach both poles. You'll need to extend the cables or just get a 34R red top.

I mounted mine without adding a secondary tray. I just used the existing holes in the tray to hold the battery down with cleats.
