I agree with prior sentiments that the G3 is hard to beat (at least, with other Nova chucks, it CAN be beat with other brands, you'll just spend a bit more money!
)
One thing I would make sure you check about the chuck you listed, is if it can be used with the lathe in reverse? Some chucks don't have the locking grub screw that allows them to be used with the lathe in reverse. Without that grub, the chuck will just unthread itself if you flip the lathe into reverse, which can be quite dangerous.
I have a couple of G3 chucks, and one other (forget which model, but like the one you listed it has some restrictions) and a crap ton of Nova jaws. I ended up getting a Record Power chuck, which is compatible with the nova jaws. Its a bigger chuck, which I use with bigger bowls, platters, etc. Right off the bat, though, you could tell the Record Power chuck was better engineered. Its also sealed to limit the rate at which dust gets into the chuck...this is a problem I've had with all of my Nova chucks: They collect dust inside like no tomorrow. I've had to clean them many times, otherwise it gets harder and harder to open and close the jaws. In the nearly three years I've had it, the RP chuck has never needed to be cleaned at all.
I've also had the opportunity to use one of those quick-release EWT chucks...and, if I ever get around to buying ANOTHER chuck, I'll probably buy one of those, or something else with quick release capability. I've always hated having to unscrew/rescrew jaws. The quick release chucks are SO freakin nice. It would just be a rather hefty investment, after collecting all these Nova jaws, to switch to one...but there is no question that the EWT chuck (which is also sealed against dust, so slows the frequency you need to do a thorough cleaning) is much easier to use, far less hassle.
If you are going to invest in a chuck, after having bought too many myself...my recommendation is, spend some money, and get a really good one. It's worth it. Even though the RP chuck is not top of the line, its been so much nicer to use than any of my Nova chucks. Haven't had to clean it once, it works with much, much larger items (although isn't all that much larger than the G3), its gearing moves more smoothly, and it takes less force to open and close the jaws, they are much more accurate (once just a little bit of dust gets into the Novas, they start to get "sticky and stuttery"). Anyway...consider before you buy! Quick change chucks in particular, IMO, WELL worth the money.
