My advice is to consider buying a Dillon 550,it's a progressive machine. Initial cost is probably more than you would like,but it's a good investment. It will reload ammo quickly and accurately. You can save a little by buying Lee dies (it's what I use on my 650) and do a lot of comparison shopping. Midway and Midsouth seem to be the best places to get new .223 bullets,hit the gunshows for powder and primers. +1 on getting a decent reloading manual and dial calipers. YMMV.
