As stated above, the durability of ultrasabers is second to none. They are widely regarded as the best that you can get for that purpose, and if you dont believe me, check this out.
It's an older video, but they still hold the same standards.
As for sound, in my opinion, dollar for dollar, the Obsidian option that Ultra offers is the best board that you'll find. There have been alot of breakthroughs in this hobby for sound, mainly the Crystal Focus (which is out of most people's price range), and the Petite Crouton soundboard (which is kind of a CF lite). They have their own strengths and drawbacks, but none of them compare to the Obsidian soundboard in ease of customization or sound quality (especially at that price!) I direct your attention to this video to tell you more about it!
Best part about the Obsidian? They'll install it for you, before it ships! If you went through TCSS and didn't want to risk frying your own board, you'd have to send it to a sabersmith, and fork out another couple bills, not to mention the time it would take your saber out of your hands.
These ARE the sabers you're looking for my friend. All you have to worry about now is your costume, and we have plenty of advice in that department too!
