Well I look at it like this.
My V1 Vf-1J cost me $70 back in 2001. I whined that I wanted something better and would pay more money for it.
My 1/48 was $120 in 2003. Loved it, but when I compared the 1/48 to the V2 VF-1, and considering how much I paid then, to the quality and finishing to what I'm paying now, yes, I'm fine with the price. But only with the V2 VF-1.
The VF-0, SV-51, and VF-22 are overpriced considering their fragility and issues... (K, not alot of issues with the VF-22, but still why overpriced when it's still breakable plastic.)
So it's a balance between the different lines. Then again prices are also determined by the shipping from the sizes and weight of a box.
Now, lets look at other figures that I collect. I standard 8inch Good Smile Figure a years back use to be around $30 to $40... Most these days go for $80 to even $120!!!
And lets be honest, the price 1/100 Vf-25 by Bandai, should be more of an issue.
