Mornin' Kevin. Sorry to hear about your dilemma with your new chuck, but that is what a lot of folks are like today. The d*** h**** will lift anything.
I haven't got a chuck for sale but thought I may be able to try and point you in the right direction.
IMO Any reputable scroll chuck will do the job you want, ie - Nova / Axminster / Sorby / Multistar. What you should look for is, 1/ Make sure the spindle thread fixing can be changed at a later date. This is if you ever change your lathe. 2/ Preferably one which is operated by a singe key. Twin bar operated scrolls are cheaper, but not as convenient to use. 3/ A chuck for which you can purchase many different sized jaw sets. You don't have to buy these, but as you work you will find you could use the odd different size, and at least they will be available.
Also don't forget that most decent chucks are not that expensive, say £100 - £140 will get you a fairly good one. The biggest expense is always the jaw sets if you want to branch out. 2 extra jaw sets can cost as much as the chuck. This is the reason I say you should be able to take the chuck with you if you change your lathe. Let's face it a Nova with all the jaw sets would set you back close to £600 +. They ain't cheap things.
I wish you good luck in your quest, and hope this is some help.
