yeah, the obi saber by MR is a bit off in size, i agree there. the vader esb saber is real close in size. the graflex ones are close too. from what i read over on TCSS the maul is pretty darn close as well. if its off, its not by much. and there are lux convert kits coming for the obi, and the maul sabers, to turn a show sabers, as they are stock, into the duelable sabers with removeable blades.
the obi's biggest point is in the neck. theres just no way you can have it the actual size and duel hard with it without it bustin on ya.
and if your goin with a lux, and a 1 inch blade, it has to be large enough to fit the blade and metal blade holder that it needs.
im not sayin anything bad bout Jeff, cuz i never dealt with him or bought a saber from him, im just sayin on the behalf of MR fx sabers, theres nothin wrong with them and they make great sabers once the lux convert is done to them.
the convert, retainsmost all the origianl functions after the convert.
all sounds are the same, only thing you lose a bit on is the grow retract effect. the MR board ramps up and down the power to 1 single led lux, mounted in the hilt. theres no electrics in the blade at all, just a diffuser with a reflective piece under the tip.
you still get a slight grow retract effect even with the single led lux, just not as nice as a string of 64 leds do in the stock blade. but for a fully duelable saber, well, for me, its not that big a deal, and a dealer at the con last year i went to seen my converted extra vader saber, and went jaw to the floor, when i said can yours do this, and puled out the blade, and hung the hilt on my belt.
and brightness compared to a stock MR fx, well, the luxs make them look like dim lil lights. the luxs are way far brighter. and after the guy picked up his jaw off the floor, he said how much, and i sold that saber to him for 200 bucks.
trick is to find one with say, a dead spot in the blade but everything else works fine. grab it cheap, that paticualr saber i paid 50 bucks for off ebay. spent 50 on the convert parts, sold for 200 and made a 100 in profit.
so anyways, the MR's arent bad sabers at all after the converts are done to them.
