My Luke ANH Graflex. Wanted a lightsaber for more than 20 years before knowing there even was such a thing as a Graflex. Once I knew, I started hitting up every camera store and swap I could to get one (this was back in the day when they were going for $300-$400 on eBay, which I wouldn't pay).
I was on a business trip at a conference and during the lunch break I took a walk and came across an old camera store that looked like a tornado had swept through it. Stuff was everywhere. There were a few press cameras on the shelf, so I asked the young girl behind the counter if she had flashes for them. She picked up something and put it down and then grabbed a Kalart flash. I said "that's not it, what about that other one?" and she grabbed the "other one" and put it on the counter. After 20 years, there it was, man, like it was waiting for me to come and get it. It was unbelievable.
I asked the price and she just shrugged her shoulders and said, "How about ten bucks." I said, "fine."
When I saw Star Wars back in '77 I thought that saber was the coolest thing I'd ever seen, and I still do. I'll never sell it.
