I've had the Veritas for several years. Used as intended - in place of hand scraping - it is a gem. No more hurting hands and wavy surfaces. It does take some time to figure out how to properly set it up. DO NOT use a "flat piece of wood" when initially inserting the blade and setting blade depth. Use something that is very flat like formica countertop a a piece of glass. Adjust the mechanism up to about ~5°-10° from verticle, then set the blade. Test. You only want the wispiest shavings or none at all. Start adjusting the blade forward, or bowing the blade, until you start getting .0005"-.001" thick shavings, if that thick. The shavings should look like single ply toilet paper. For use on hardwoods, not softwoods.
Play with it for a while. Try different angles and amount of bow in the blade. I know I questioned the wisdom of buying it for a while until I learned how to properly set it up. I use it primarily as the final pass after a smoothing plane, sometimes instead of a smoother.
I can't directly compare the Veritas to the LN or Stanley 112 - I haven't used them, but my thought process was I can get an old Stanley for $100, have to buy a blade for $20 +, spend time fettling, and still not have the precision of the Veritas. I can get an LN for ~$60 more and not have the flexibility of thin or thick blade. It was a straightforward decision for me.
