epi is pretty good if you dose high: 60-80mg; i actually did a pulse cycle with this and worked pretty well for lean gains plus strength
hdrol is my fav at 100mg a day - solid strength gains, prob put on 10lbs
sdrol - tried it at 30 but stopped after two weeks, started feeling sick to my stomach, but it kicked in quick, got really strong
you can buy sdrol for cheap - i think pulsing it would be a good idea to minimize side effects, i.e. take it 3 or 4 times a week, preferably on workout days
