In my opinion, Dragonball cels in particular 
Mirai Trunks, Vegita,"Fusion", and SS Gohan 2 
cels are hot items. The prices just reflect the 
short supply and the large demand that is going 
on right now. Dragonball Z is a very popular 
anime and is getting increasingly so, at the same 
time many collectors have taken a lot of 
the "prime" cels that have been on the market. 
But more and more people have decided to want to 
collect these cels. I would not be at all 
surprised to see the prices of them go even 
higher. What is strange to me is that people are 
so shocked by it. But if an Evangelion, Lodoss, 
Miyazaki, or AMG cel goes for such a price no one 
seems to think that is strange, although it could 
be argued that the mass market appeal for those 
series is not as high as Dragonball Z or GT. Of 
course it could be stated that they are high 
because of their rarity, and the anime character 
design is more intricate or sophisticated, but 
the same argument could be made for a DB Gojita, 
Vegitto, Broly, or Mirai Trunks cel. Dragonball 
was a very long series, so there appears to be 
an "endless supply" of cels, but the reality is 
that is not so, especially when you consider the 
rare cels and great characters that have had only 
short appearances, given the totality of the 
series. Although, Son Goku is the ultimate hero 
of the Dragonball series, in the States he is not 
the most highly sought after (not yet anyway) 
since he appears in almost every single episode, 
his cels will be the most plentiful and the 
easiest to acquire. Thus, his collecting appeal 
and price (high supply) have tend suppress the 
pricing of his cels, except when he changes forms 
(i.e, SS2,3,4,etc.)Although Vegita, tends to be 
the wild card in all of this. He appears quite 
often, In many different forms, and yet his fan 
base is larger than the actual hero of the series 
(at least in the USA). So, again, in my opinion 
upon close inspection, the cel that is being 
offered (Trunks)although now seen as expensive by 
some, may actually be set at a reasonable price 
given the popularity and the rarity of the 
appearance of the character in the series. I 
however, am not a strong fan of this particular 
character. But, at the same time if someone is 
bound to make some money by selling what he owns--
more power to him/her after all it is their free 
choice to do so. You have the choice to say no 
it's too much, no matter how much you may want 
it. And many times, things don't get sold (not 
the first time anyway!)
