@Toromino https://www.techradar.com/news/best-entry-level-dslr-camera might be a good list to start at!
unfortunately affordable here is gonna be... well, yeah, it's going to be kind of expensive. however, it'll give you a sense of product lines. i'd say canon or nikon are probably going to be your best bets, especially because a dslr will take any lenses of that type, since there's no such thing as a 'dslr only lens'. well ok there might be, in some very specialized fields, but what i'm getting at >
@Toromino is that the canon and nikon lenses a dslr takes are going to be the same canon and nikon lenses that have been in use for film SLR cameras for years, and years, and years, and years - like, solidly since 1950 if not earlier. that means you can usually find a pretty good deal on some basic lenses, and occasionally good finds of the "uncle jimmy loves his cameras but we don't know what to do with these now" type at estate sales, etc. on the secondhand market.
