Ive been playing/ collecting 40k for over 15 yeas and i play everything except space wolves and eldar, and sisters but thats becuz no new models or codex, cri erytiem. Do u know anything about it yet or what army or play style u want? I recommend getting one of the starter sets if u like the style of the armies in them. Theres Dark Angels Space Marines vs Chaos Space Marines (SM) And Blood Angel SM vs Tyranids. Each = $125 USD Thats also no paint or tools If u dont get a set then just to start is: Example: normal (SM) $75 core rulebook $50 army book $30 commander $80 x 2 troops $40 x 1 fast $40 x 1 heavy $46 x 1 walker $57 x 1 tank ~$50 in tools ~$75-100 for paint
