Ive got some options to buy Lego and want other opinions on whats worth it.

So ive got 200nzd (115.91usd) to spend on Lego and want to get others opinions on stuff I will convert prices into usd to make it more understandable for most. First there is the Cole titan mech for 220NZD (127.50) this is my favorite mech but idk if its worth the 220 because i cant find any cheaper options on it sadly. Second is the Temple of the dragon cores which is 182.49NZD (105.74USD) I do like the build but I dont know if its worth spending 182 on it. Third is the Fire stone mech...
