Another option is multisize collet chucks. https://www.ebay.co.uk/b/burnerd-collet/bn_7024823313

Still quite a few around and a set will cover a wide range of sizes with very good runout. There are several types but mine (EC?) go up to 38mm with no gaps. You might get a chuck for £200 and a set of collets for a similar price if you keep your eyes open.
