AS has been mentioned the hand dies can get expensive quick if loading for several calibers.
I have been loading for going on 30+ years using a standard ram type press. I haven't ever shot competition, but in the course of time I have loaded thousands of loads which would easily group 1" or better generally at 100yds.
For the most part I have used Hornady, RCBS, and Redding dies on either a Herters or RCBS Rock Chucker press. I have also done a substantial amout of range load development using a $30.00 Lee Reloader press and also a RCBS Partner press.
I generally weigh out charges on my Uniflow powder measure and record them then simply work up loads within the range indicated for that particular powder on the stem of the measure.
For the standard calibers, in factory hunting rifles, I would suggest going with one of the standard type presses and some good dies. Good is a realitive thing, as I have loads which shoot better when loaded with lee dies as they do with Redding dies of the same caliber. Not sure why, as they all mic out the same, but it's hard to deny the results.
For a full competition rifle, well thats going to be your call as it will have tighter tolerances and you will want to match everything up as near perfect as possible.
One thing to watch on those E-bay press deals is the shipping. I picked up a really nice RCBS press for $38.00 a couple years ago, however the shipping on the thing was $20 due to the weight. Just something to be aware of before bidding on one without the shipping cost listed.
