Thanks everyone for your comments! They were really quite easy to make. The handles are actually miniature replicas you can find on ebay for under $20 each.
Just do a search for ".45 lightsaber replicas"
The Anakin saber (on the right) I just used some JB Weld and a beer tap handle ferrule, you can get on Amazon for $5
The Darth Vader on the left was a little trickier where the bottom of the lightsaber actually needed to come off so the threads of the perlick tap would go up into the base of the lightsaber. (you'll have to use some "force" to get it to losen.)
Then I just took the chrome collar off of the Perlick tap and again JB Weld them together.
In hindsight, I could have used ferrules on both lightsabers, but I did Vader first and "assumed" the bottom would come off of the Anakin saber, but alas it did not. So I improvised.
All total I may have $45 in both handles. Well worth the conversation they produce. And, they're still removable if you decide to change 'em out for Yoda or Count Dooku.
