Wayne SPF33
#4 in Up to 1/3 HPFull review
A light, low cost pump for a shallow basement with modest water. The 1 year warranty makes it a budget pick rather than a long term one.

Little Giant BSP50V
#12 in 1/2 HP and upFull review
For a tight budget or a spare pump, where 1/2 HP flow matters more than a heavy cast iron body.
