Here is my review of the MRFX ESB Vader with a TCSS conversion kit and a 3W luxeon I did myself. I got the saber from Ebay for $60 shipped. It was supposed to be a floor model with light wear, I got a brand new one sealed! I orderd the TCSS conversion shortly after Tim got them back in stock. The only other FX saber I have handled is the Anakin and I was really disappointed at its quality compared to my Luke Graflex. The overall quality of the Vader seems to be alot better as well.
Overall installation was easy, thanks to the tutorial, and the only problem I really had was the cotter pin removal in the on/off assembly. Adding the alum blade holder made the hilt quite a bit heavier, I shaved the blade down to 34" , installed a mirror and some mylar. It doesnt have any play in the hilt... its rock solid! Two inches off the blade makes a difference imo, and I like it better.
The image shows a copper colored hilt, this is just the lighting in the room
