Having owned all of the above mentioned chargers over the past year or so, (have the ICE right know) I would definetly reccommend the ICE.
The Orion chager is a pain to navigate the menus, the motor run in is suspect(newer version suppose to have this fixed), rather cheap looking and the price is rather high $180 or so. Newer version can charge Li-Pos.
The LRP 2, good charger, can't charge Li-Pos, also rather expensive $160 os so.
APS charger, good charger, can't charge Li-Pos, buttons are a pain to press. Motor run and checker very nice. No discharger, but most people use discharge trays anyways. Also rather expensive around $170 or so.
ICE, good charger, easy to navigate menu, easy to setup and use. Charges Li-Pos. 5 year warranty but no backlight. Really only complaint I have. Also very good price $130 or so.
