Managed to get the two common astro droids from the same seller for about $25 shipped each. After searching for these at all possible locations when I was at DW a couple of weeks ago and coming up empty, I figured that's not too bad of a price.
That Chopper droid is a bitch to find on ebay though. I should be happy with just having the OG Chopper and not worrying about any redecos that may come along. Not sure I'm there yet, but it may be soon.
I don't give a **** about the BB droids.
