Dremel Multitool keyless chucks

You guys may have already seen or use it already. Sometimes I use a Dremel for inlay or polishing and I get sick of changing collets so I can use different sized bits. I saw this recently thought I'd share, its a keyless chuck that takes from 0.5-3.5 mm bits as in all things you can get the original Dremel at approx $17.00 or a Chinese copy for $2-3 dollars inc shipping. I'm sure the Dremel version will last longer. I believe it's available at The green shed or eBay.
Hope it helps
