Likewise!
How many more do you have to go?
I might call it quits at 6. I might go for a 7th if I can find the Purple Helmet - Green Torso - Orange Lightsaber version. With that one, I'd have one of every color in almost every part. The only pieces I'd be missing are a Red Torso, Purple Right Arm, and Green Lightsaber. I'd have to buy three different Vaders to get those last three pieces and that seems unlikely unless they show up somewhere for cheap. On the other hand, there are three variations for each remaining part I'd need, so I won't close the door on it.
I'm tempted to get some extras with Yellow/Red/Blue lightsabers just for my displays of original vintage Luke/Obi/Vader's without weapons. I don't like using repro stuff, but original sabers with tips are tough to track down, so $10-12 a pop isn't all that bad.
