tips for starting death guard

I havent actually collected a full army in both age of sigmar or 40k I just have bits of aos armies cause warcry is really fun but I want to get into 40k and im thinking of collecting death guard as my army but im a little confused on where to start im mainly wondering if I should wait until the codex comes out for the new combat patrol or just get what I enjoy right now cause I know its not good but I think the malignifier is super cool and want that in my army. the current combat patrol just doesnt interest me at all any tips or alternate ways to start collecting though would be nice cause I dont really have any local stores that offer discounts and online places dont have many good discounts for death guard so any advice would be nice I already have paints and hobby tools so im just here for figures now
