This is a bit more expensive but a real eye feast. Take a look in case you may like it. It's only 45mm long. Comes in several metal with its different prices. I have the original design, so it's not as nice as these. I didn't think to mention this one before because I thought it might be expensive. But it could be affordable, depending on your definition of affordable.
The metal in the picture is titanium. If you do decide to buy this one, you may consider buying an extra battery in case your current one runs out of battery, so you'd have one to use while charging the other one.
