I use the type in the second link to sidedress corn and cotton, I'm very Happy with the job they do.
For all other spraying, I like GreenLeaf's Airmix nozzles. I've used a lot of different tips, and these seem like they're a good compromise between not drifting and getting good coverage. They seem to not get as fine as others at higher pressure, they're cheap, they fit a standard cap, and they plug less than some others I've used in the same size. I spray everything from Roundup, Gramoxone, soil applied herbicides, fungicides, defoliants, and everything else you can think of with them. Yes, even foliar applied fertilizers.
TeeJet has one similar to this that I've tried, but I thought it drifted worse at higher pressures. Hypro's ULD tips make for a really coarse spray that doesn't drift much, but they're horrible about stopping up.
Not sure why Dultmeier doesn't list a price, but they should be around $4.75. Think I've bought them from Phil Jensen, and I'm pretty sure Shoup carries them, too.
