I see plenty of vegeta cels around $100 and up, 
but to find a mirai trunks for $100, well it 
might be just his hair or hair and a nose for 
$100... They are hard to find and usually sell 
for way more than expected. GT trunks is alot 
more common and he kinda looks like mirai trunks 
except for the clothing. You can get GT trunks 
for $100 and sometimes less.

hope this helps
