If you have a Blizzard, I recommend BlizKick. It is vastly superior to every other rekicker available.
For other boards, there are a couple of options. Apollo owners can use RemApollo, which can use BlizKick's add-in modules. For owners of other cards, I think that MuLib (MMU library that enables the use of virtual memory, etc) ships with a rekicker.
Relokick is unique in that it doesn't need an MMU (memory management unit, part of the CPU, and not fitted to the standard 68000 or 68020 chips) to function.
