Define "work just as well". If you're looking for something with the same current rating, 5V inputs, and you don't want to bodge 3-4 individual SPDT relays into something like an H-bridge, then I don't think there's actually anything available that's cheaper than the Spike. There's some multi-channel relay boards, but you'd have to rig up 4 of the channels on there to turn it into a Spike equivalent.
