gyrfalcon, another alternative for splitting wood is a tool known as a froe. Using a one hand sledgehammer, you will be able to easily split and not take out your back. I have seen a large froe at www.lehmans.com and smaller one at www.garretwade.com. My hubby made a small one, about a foot long and I use it to split 6 inch logs for kindling and smaller pieces. I'm 5'3" with back problems for years and I can ably split 16 inch rounds using an Ames Super Splitter axe we got at Lowes. I feel that if you're not sure how your back will handle it definitely look at the smaller electric splitters. They work quite well. We are also installing a Tribute soon and will be using 12" to 14" splits my hubby used his chain saw to cut down from 18 inch logs we had cut for our other bigger stove. I split the leftover slices into 4 inch chunks and will use those in the Tribute as well.
In case you're interested in seeing how a froe works, here is a cool video from Taylor guitars showing a guy splitting a large round from a big Alaskan Sitka Spruce: http://www.taylorguitars.com/see-hear/Video.aspx?file=CuttingSpruce_high.wmx
