When I set up my reloading and gun hobby room, I already had 45-year old Rosewood Desk for my books, manuals, and study materials. After a bit of looking, I bought a Husky work bench at Home Depot. Comes with a pegboard back and shelf, two drawers and two good sized shelves for my die sets and supplies. The bench cost $198 a few years ago.
As I use RCBS equipment, I got three of their mounting plates, one at each front corner for my Rock Chucker and Turret Presses, and one in the front middle for mounting my case trimmer and powder thrower. I have plenty of work space, and can move all my equipment with the turn of a few screws when I need to use the bench for gunsmithing. It's big enough for my Dremel Workstation and tool kits that I use for smith work, stock bedding, scope mounting and pistol cleaning. The bench comes with an aluminum top so it's easy to clean.
As to storage of powders, primers, and brass I use plastic tubs that stack neatly, also from Home Depot.
Good luck with your choices.
