Which blade should i get?

Hello everyone, i’ve been playing on outdoor tables for like 6 months now. I decided to start playing indoor and get some courses. My teacher is saying that my level is above amateur and should get a modern blade because the one i have right now is good but too old for modern rubbers and balls. Right now i’m using a 40 years old stiga offensive blade. I tried his training racket and it was day and night, control was ten times better. My budget is around 50/60€ and there are too many choices. My dream blade would be the boll alc but too expensive right now…maybe one day (: Here’s the racket i’m using right now. Thank you!
