Should I trade my Yamaha Blaster for A 400ex

i would much rather have a 400ex.... just because all i do is trail riding... i was planning on doing mx and drag... but the blaster needs to much money into it before i would have any chanse at all
 
i'd go for it 400ex's are imo the longest lasting most durable best trail quad out of the 400cc's if i had the money i'd get that, or the suzuki lt-r450 >:)
