I've been playing the hobby since I was 12 and over the last 6 years until I got a job scrounging up cash for models was difficult. I remember my first (when the battleforces were only $90 bless those days) battleforce I worked by cleaning cars, cleaned fridges, and doing chores and saved up enough money to buy that battleforce when I was 12. So I can totally relate to the position this kid was in. Now that I actually earn money, buying models is much easier, but even when I was 16, a $33 or some odd box of models would of taken me 2 months to get. I got twenty bucks allowance a month, and not every kid is as well as as I might of been. Honestly I would of called that guy out who called you terrible, I think it's completely rude.
As being part of the younger minority of the Warhammer population, not having a salary job, or being able to work as much is a huge burden when this is the only hobby that really makes you happy. As long as it was clear and ok with the his opponents and it CLEARLY looked like models I would of given that kid a pat on the back and said go ahead.
There's no such thing as too many crisis suits.
