If you are looking for an inexpensive Santoku, consider this one. It's a hybrid with European style handle and forged stainless blade, good value knife for the price. It's easy to adapt to if you are used to standard chef's knives. It's worth thinking about if you want to expand your food preparation skills. But you may also want to consider a real Japanese santoku someday.
As you know, santokus are originally a Japanese knife intended for chopping vegetables and boneless meat. In Japan, knives are often made from inexpensive high carbon steel -- steel that is very hard and keeps a very sharp edge but rusts easily. The blade edge is thinner and more acute edged, with a 15 degree bevel on both sides, instead of the western 20 degree bevel. Traditionally they have an unfinished wood handle.
Such a knife cuts well, but will rust quickly and the handle will split if washed in a dishwasher, or simply left wet. Knives that rust or are not dishwasher compatible don't appeal to typical American cooks, so many mass market Santokus use stainless steel, which is rust resistant but won't hold an edge as well as a high carbon steel blade.
I mention all this because this knife is far from a traditional Japanese Santoku. It has a heavier stainless blade and European style handle. Its blade bevel angle seems to be 20 degrees, not 15. Still, it is lighter and more agile than a long heavy chef's knife, the most common prep knife in US kitchens. So it gives you some of the advantages of a real santoku.
For quick veggie prep you may want to consider an even lighter, ultra sharp knife, like the true Santoku. You can find those here on Amazon in all price ranges. Be prepared to baby them. The high carbon steel will rust if left wet, and the bare wood handle will split if you put them in a dishwasher. But the blade -- wow. They are like razors and really cut veggies quickly with little effort. So, that's the tradeoff: easy maintenance versus efficient chopping. If you are disciplined about maintaining them, true santokus are wonderful tools.
