I picked up the Yoda and Luke this morning at my local Radio Shack. The Vader was out. The manager said he was selling these things like hot cakes. He had 50 over the last 2 weeks and is down to a few left. I saw a couple more Yoda and Lukes. Plenty of Maul laser pointers.
Construction is plastic over metal. ( 3 ) AG-5 batteries and plenty of room for a larger LED (i.e. Rebel).
There not as bright as they should be but there is plenty of room for improvement. The hilt is not big enough for AG13 batteries so getting power to a Rebel LED could be a challenge.
I have comparison pictures between these and the MR scaled versions of the Luke and Yoda. The Yoda appears to be close to .45 scale just like the MR version...
P.S. I just realized that these are made by Master Replicas!
