The main magnet to go with this particular company was their Deus Ex Machina product line.
25 mmBeside the full bases they make also 30, 40 and 50 mm inserts which can be easily glued to normal plastic base of proper diameter. They are quite thin so your squads will not be unnecessarily exposed to opponent fire.
In turn, all bases from Tauran refinery line are extremely thick. They are perfect to make your Independent Characters (or other special models) really standing out from the crowd.
Third line which I picked was the Fens. These bases I will obviously use for some Nurgle followers. Nice bubbles, see...
This last one is 120 mm oval base which triggered promotional discount and gave me excuse to drag all this stuff from New Zealand.
