Serf 'rett is about right. But you don't have to start out full bore. You can go slow.
You can start with $150 and be minimally equipped for one caliber, and can expand from there as you have the money and feel the need for more tools. But you will have spent
nothing on items you will later discard or outgrow.
$204 will get you up to a really nice setup for one caliber. $287 and you have a really good setup.
$422 and you have just about everything you need to load one caliber, 100 rounds per hour at an easy pace or up to 200 if you are faster than me (and I am slow) on a continuous basis for as long as you want.
(NOTE: These dollar figures are from June/July 2010, but you should still be able to match them if you shop carefully.)
Budget another $100 for miscellaneous small tools plus $50 per additional caliber.

See my "10 Advices for the Novice Handloader" here, post #10. Post #9 has a bunch of links you might find useful. They are largely threads from other people new to or asking about reloading/handloading.
