JQ sabers is also in Europe [UK] and like Force Relics they also do fine work and are another great choice for European saberfans.
TCSS does not produce completed sabers but they make excellent parts to build one yourself like a 'real' Jedi/Sith, if you have the knowledge to do so, or are willing to learn [the TCSS forums have excellent tutorials] and TCSS parts are used by many top pro sabersmiths - they are the 'gold standard' for saber parts.
Makoto and Parks sabers use a LED-string in blade technology similar to those used by Master Replicas/Hasbro Force-FX sabers rather than the high-power LED in hilt technology used by most custom sabersmiths nowadays. Those can be quite bright compared to FFX but are more vulnerable to damage under dueling impacts since they have components inside the blade which is why most sabersmiths now use in-hilt LEDs.
Vaders Vault, Genesis Custom Sabers [Madcow], GG/LDM are top-of-the-top among pro sabersmiths for a reason; they have pioneered many of the 'industry standards' and 'best practices' in the saber hobby/business and their sterling reputations for superlative quality and performance are well known and deserved.
There is one you have mentioned Evol that I have not..that maker also has a reputation, also for a reason, and I can say no more due to rules here but look and you will find your own answer.
One thing you should be realistically aware of is that modern LED technology cannot yet produce saber props as bright in full direct daylight bright sunlight as the depictions onscreen in movies or in videos where the physics of camera function make saber props usually appear brighter than they do to the human eye. This is not meant to discourage you at all but to inform you so that you will not be disappointed and think there is something wrong when your find your custom saber prop isn't as bright as a noonday sun in the tropics or on Tatooine. ;)
Which is a good thing really - for one of our saber props to look as bright in real life as they do in the movies on a bright Tatooine summer day they would have to be bright enough to OUTCOMPETE THE SUN's brightness which can BLIND one to look directly at eh? A saber prop 'bright enough' to do that would be TOO bright for safety [consider that the fictional lightsaber is basically a 10,000 degree hot meter-long plasma cutting torch - real world welders have to wear special dark lensed helmets to protect their eyesight from much less intense cutting torches...maybe in FICTION Jedi/Sith can somehow protect their eyes with the Force ? from their lightsabers brightness and people around they wince away from looking directly at them as IRL we do from looking at the sun but in real life an illuminated saber prop that "looks like a real one during the DAY and the night" would be DANGEROUS to oneself and bystanders even without being able to cut anything lol].
That is not to say our prop sabers cant be QUITE bright - in the decade I've been in this hobby our sabers have become MUCH brighter and the present generation of multiple-Rebel/multiple-Cree emitter stars are very very nice and bright indeed and products using them by any of the fine sabersmiths in the Guild or MC here can be MUCH brighter than the MR/Hasbro force FX sabers but PLEASE just have realistic expectations they don't/can't look like the movies in full daylight bright direct sunlight and wouldn't be safe for mere humans to own if they could.
MTFBWYA, Happy Holidays and best of luck with your choice.
