If you think it is a good idea then I say definitely start collecting Frieza again. It will definitely be easier to go with just him and King Cold than the whole squad...unless you get the complete Freeza's Force lot but that defeats the purpose doesn't it.
I thought it was funny that you listed the Zarbon and Dodoria models one day on ebay without the Frieza, and then the very next day you relisted all of your Frieza stuff including the Frieza back with Zarbon and Dodoria. I guess you changed your mind AGAIN.
Maybe you had a 2nd set of them. Didn't check. Just went with what I saw.
