I have a Beall, a PSI and a CSUSA. I use all three and the er32 collets (bought on Amazon) fits all 3 chucks nicely. The Beall is my favorite because it has far less run out than the other 2, is a much smaller body without the knurling (once you grind all the skin off of your left pinky a time or two, you'll understand why that's important) AND of the 3, the Beall is the only one of the chuck bodies made in the USA.
The Beall costs nearly twice as much as the other two, but IMHO, it is a more accurate tool. Any of the three chucks are somewhat dependent on the quality of the er32 collets (which all seem to be made in the same factory in China) and any of the three should meet your needs. It comes down to personal preference.
Personally, I'd pass on the Wood River chuck as it is a morse tape chuck, which kinda defeats the usefulness of a collet chuck, as it is difficult to put anything "through" the chuck because of the Morse Taper.
