If your not dead set on Snapon Mac tools offers a locking stlye of these in 3 sizes. I have wanted one of the Snapon ones for a while in green but never went for it. Due to a great discount at work for MAC tools stuff. Only negitive I have found with the MAC ones are there not made in the USA. But I love mine regardless and will be buying a back up set I like these 3/8 spinner handles that much.
X6EDLA 6 inch best one all around and my go to. $42


X10EDLA 10 inch a bit long for my needs but have it and use it randomly really useful on old cars. $40
X18EDLA 18inch dont own but seems stupidly long lol. $57
Sorry i'm not much help
