2 main reasons:
(1) So far from my own research, I cannot seem to find a fan-made one, for around the same price of the Rubie's one which is roughly £600ish pounds for me. I would not like to spend £1000 for an entire set(armour and helmet).
(2) I really want to get a ready made one, instead of having to trim and build it myself, because I am very anxious with doing that. I understand it may not be the best fit, but I am standard size.
So my question is, are there any others available that are relatively cheap(my budge being around £600ish to £700ish) and ready made to wear?
Additionally, I would like to wear it for trooping around!
