Mine are all old ones, so can't say from personal experience about newer ones. But If I were to buy a new one, the one you bought is nice. I've also had very good luck and been impressed with the quality of Lee Valley's Veritas line of tools.
The key things to remember about draw knives are:
1. As with all woodworking tools except a froe, sharp is important
2. Remember to use it bevel down. In other words, the bevel should be face down on the wood. Tis gives you better control over the depth of the cut.
3. Whenever possible, draw up the tree, not down it. Grain on most kinds of wood have a direction. If you start to draw your knife toward the base of the tree, you're more likely to get your blade into the grain and raise more than you want. When you have a board or a sawn piece, it's easier to read the grain and avoid this. But when you have a stick, then use the direction the tree grew in to help you. If you have to cut down towards the roots, then take very shallow cuts and watch your bevel. For this, a spokeshave works better because it isn't as open and can't dig into the grain like a draw knife.
