I have a friend with a Land Pride back blade, but that's my only exposure to their products. It is fine, but I didn't think that it was above and beyond other quality blades, such as a Woods. Generalizing, before only looking for a brand, I would get versed in the specific implement, and find the best one, whichever, in your price range, that will serve your needs. I've found that any given manufacturer may have some great stuff, but not all that they offer is tops. So, you may find a tiller in one brand, and an auger in another, that suits you best.
For what it's worth, I have a King Kutter tiller (48"), which I use 8 or 10 times a year. It is above and beyond what I need, and I have $1400 in it, new.
