chucks are the second most expensive item in wood turning. The lathe being the most expensive.
So it's not worth skimping on a chuck.
A good chuck will save you from almost certain injury. Anyone who's seen a heavy piece of wood escape from a chuck at 1500 rpm to richochet around a small shed - will agree
Woodturning is not for people with slow reactions
The better made the chuck the less risk you take in poking a sharp piece of metal into an irregularly shaped hunk of wood spinning at over 1000 rpm
trust me - bowl turning is not for the faint of heart.
I spent a long time looking round at the different models before I bought the one I have. It's got special shaped jaws so will grip unusual shaped better than other chucks.
What I would suggest you do is find out and contact any local turning groups. These are generally made up of retired gentleman who die regularly. So any second hand turning kit tends to get offered to the group first (sounds callous - but isn't lol)
My first batch of wood turning blanks came from the workshop of a recently passed turner.
this is the chuck I have - actually made in canada, I'd forgotten that.
http://www.newwoodworker.com/reviews/onwytlonrvu.html Cost me about £130 around 11 years ago. Just glad I'm not trying to buy one today !
I only have the standard jaws it came with - never needed any other size.
Just looked at the prices on the oneway site - can you believe that 11 years later they are THE SAME PRICE !
Amazing.
But like I say, contact your local wood turning group, they're always looking for new members and they'll know where the best place to get a chuck is and bear you in mind if one of them kicks the bucket. Seriously this is not callous. I also have a box of chisels from another deceased turner. Mostly for spindle turning - but a couple of useful chisels among them.
Woodturners like their kit to go to someone who will appreciate it, so don't be afraid to broach the subject of deceased turners kit. Obviously be a bit subtle about it
Far as raising money goes, you could try selling some slings in our excellent market place
