Has anyone found any lower-cost substitutes for Chip-Quik solder?

For those of us who haven't heard of Chip-Quik, here's some info from the
chipquik.com website:

How to remove a SMD chip from a PCB:

First, apply paste flux generously to all the pins of the SMD to be
removed. Flux is important because it removes oxidation and enhances
wetting.
Secondly, use a solder iron set at 500 to 600Deg. F with a flat chisel
tip. The size of the tip will depend on the size of the chip leads. With
the solder iron, melt Chip Quik low temperature alloy (136Deg.F) along
each side of SMD.
Thirdly, continue running the iron along pins until a bead of alloy is
formed all around the chip. Maintain the alloy in a molten state long
enough to combine with the interconnect solder (melts at 361deg.F)
between the pin and the pads. Once the Chip Quik mixes with the
interconnect solder, we now have a molten mass of a new alloy with a low
melting temperature below 200deg.F. At this new low melting temperature
the pins stay in a molten state long enough to easily remove the Chip. In
most cases the chip will easily slide off the pads when it is fully
molten.
Finally, when the SMD is held down with an adhesive, applying pressure
with a dental pick will pop off the chip. As long as all the pins are
released, you will not lift any pads. This procedure will eliminate all
potential damage to the PCB.
