>>4274075Nikon D90/D300 - Canon 7D/70D. Something along those lines, Body with batts and charger can be had for 2-400 if you look around for a while (Not ebay) and a kit lens is many times either included or can be bought for 30-80 bucks.
They're dated cameras but they retain their value and they're still pleasant to use.
Hardmode? You're never gonna be able to find something like that at a retailer for 500. Maybe a used 600D or D3xxx but at least u get warranty I guess?
I got picrel with 2 batts, 5 CF cards, box and all the accessories for 350 shipped from ebay (amazing I know but it was 2022) and the kit lens I use can be had for like 50 bucks.
