A Forster set with a standard seating die is pretty cheap. The Ultra micrometer seating die is very nice but not required and will save you money.
I have Hornady dies as well and despite be inexpensive, they work very well. They're not flashy, but they work well.
You can get the Lee Ultimate four die sets for dirt cheap ($50 or less on sale) and they are really good dies for the money. They include an full length sizing die, collet neck sizing die, bullet seating die and a crimping die. Their machining looks rough on the outside, but is good where it counts.
