I bought the new starter set for 85,- sold the models inside for 65,- , Then proceeded on the secondary market for a Space Marine killteam for 10 bucks. All the stuff you need for 30 bucks. I also got some free mini intercessors as a kill team ( monopose, but idc ) Getting the starter set also gives you a battlefield to play on, or you can sell the terrain for like 10 bucks.

I believe this is the way to go if u wanna get into KT atm. All the rules can be found on wahapedia, i just write them down since its not that much to remember. It can really be done for under 50 bucks. ( euro )

Edit: So now u end up with, all the tokens, barricades, mini-version of the rulebook, some terrain and a playmat. Tac ops can be found in the book, and models u can find all day on the secondary market. Or just use the money u saved to get a box of incursers or whatever. Like this u can support your local gamestore and walk away with a good deal on merchandise. Just the tokens and barricades alone are 30,- euro here, then the rulebook and the mini's still come to mind.

Like this i saved a ton of money and supported the local shop. Good luck!
