If loading to save money, buy bulk Remington projectiles etc from Reloader supplies. A lee kit will get you going.
If you want to improve accuracy and tailor loads to your rifle, then you're not going to save much money - add up the total cost of the kit, then subtract the cost per round for factory ammo and work out how many rounds you'll have to shoot before you even break even...it depressingly high, so not worth doing if money is the main motivation.
