I have only been reloading myself for the past several months using friends equipment and or mine. Its a expensive hobby to start or can be depending on how serious you are about reloading. Lots of things to consider and lots of little things required as listed in the previous posts.
I have been researching my equipment and "wish listed" all mine on midway.com just waiting for the little extra cash to pull the trigger. Midway is running a good deal right now on the RCBS Rock Chucker Supreme Kit and it comes withs the reloading manual. As well, RCBS is offering a $50 rebate if you purchase $300 of RCBS equip. Which is almost impossible not to do.
Lee also has a inexpensive starter kit for around $100, the press and powder thrower are great but the powder scale blows so you will need a RCBS 505 powder scale if you go this route.
I have used both of these and feel RCBS is the better choice.
Once you order all your equipment and are waiting for its arrival, get started on your reloading bench. Read the posts in these forums on such before you start construction. Make sure your bench is big enough for all your equipment, then double that in size. Include lots of nice little cubby holes, partitions and shelving for all your supplies, dies and tools.
