I have one of the Tricloud walkers and they aren't an easy install. The saber is small (but apparently correct to the size in the film. I'm actually surprised at how small the film prop is...). Looking at it, I think Jango may have the best solution unless one is a very advanced installer oneself. I wasn't aware of the price jump on the hilt (I still need to install my own so I hadn't been looking) but if one were to add an install to the present price, it would then easily hit the same range as the Tusken killer (and that isn't counting extra charges for a tricky install. I've seen a dual 14350 Lith-ion install of a PC 2(?) but it was a major cram fu project over on the RPF site some years ago and the install looked like a major brain twister to pull off. Possibly the new Prism and, of course, the various CS cards would make an easier personal install since they operate on a single cell, but building a chassis and cramming in even the basics of a sound saber would still be a whole world of fun and games. Best luck.
