Been covered about a thousand times, but I'll take another stab. 
Selectables are awsome but expensive. 
lunchbox lockers work well once you are used to them.  Especially in the front. 
Lincon lockers work epic for what they cost. 

There you go.  If its a daily driver like my runner I love an elocker rear, and a detroit front.  If its a trailer queen then weld the sob.
