Axle bearings?

My axle bearings went bad yesterday and I tore it down to the carrier and it has a little scoring but it looks ok, and the inside tube has some marks on it but it looks usable, but anyway which bearings should I buy? Does it matter if they are made by "pivot works" or "all balls"? Are they all good just all long as they are double rubber sealed with double lipped seals? This is a PITA so I don't want to have to bearings for a while after this. I might get an extended axle when I put it back together. And what about installation I have access to a press but still how do u press them in and out without messing up the bearings?

we have used both the pivotworks and the all balls have had good results with both..

thanks a lot
