If you're just after a kindling splitter mate, I wouldn't bother with a GB - way too much money for the task it's doing!
I believe Axminster sells a bearded axe it calls a "Japanese Hand Axe". I believe Robin Wood has one and said it makes a great kindling splitter. It's about £20 IIRC, which you could still beat by quite a margin, last time we had an open fire and a range I split the wood with a hatchet that looked like it was used for breaking rocks...
How big are the logs? If you're talking about the short logs about 1' long which is what we got, I again used my rubbish little hatchet - you certainly wouldn't need a maul. If you are splitting big logs though, something like this would be a big help.
Alternatively, you can get fibreglass handled hatchets and larger axes pretty cheap these days - not great quality, but as long as you can put a half-decent edge on it it'll do. You could probably get a smaller one and a big one for £20 if you looked around...
You may also want to try a kindling knife. Just a big whopper of a chopper, some people get on with them better than axes when you get down to smaller bits of wood.
Hope this helps!
All will rise again for a better day; earth, green, with waterfalls where eagles hunt their prey
