They say every Jedi builds their own lightsaber

So do Jedi have a shed full of old amateur lightsaber builds that cause RSI problems or intermittently sputter and die?

And is every Jedi perennially unhappy with some feature of their lightsaber, distracted from fighting Sith by ideas for how to improve the design, as soon as they save enough to order more parts?

Wait do Jedis do group-buys of lightsaber kits to take advantage of volume discounts? That shit must be expensive in small quantities
