Thanks everyone for the replies and welcome messages! The review really helped and I decided not to buy the Jedi Interceptor for now. I started my Lego journey by buying Rey's Speeder and Carbon Freezing-Chamber because I didn't know how else I could use an Amazon coupon I got for my birthday. As a newbie I'm mostly excited by three things: 1) iconic minifigs 2) iconic scenes 3)iconic vehicles
I really like Rey, Boba Fett and Han Solo so I blindly went for those two sets on Amazon; I also got the recent Imperial Trooper Battle Pack while shopping in a general store cause I just couldn't live those nice Death/Stormtroopers on the shelves!
My current "budget plan" is getting just one medium sized ship and the going on with smaller sets until the TLJ wave arrives: as for the medium sized ship I can't decide among the U-Wing (50 euro in Italy), the Y-Wing (65 euro) and the two X-Wing from TFA (80 euro each).
The U-Wing for that price is really an awesome deal; I love Rogue one, watched it twice at the cinema, and I love the U-Wing in both the movie and the Battlefront DLC; still, there's something off in the design of the Lego version, it looks awesome with open wings but "odd" with closed wings; then again, it contains the two main characters minifigs which I really love, and sadly there's no Rogue One set in the summer wave so I'll probably end up buying the U-Wing anyway in the future. As I'm writing this I already feel the urge to open Amazon and buy it
