Bob's post reminded me of a propagation table a friend uses in his green house.  He
built a plywood table with a low rim, put down some pipe warming tape (the more
expensive type with a thermostat) and covered it with pea gravel.  This would cost less
than a set of mats and thermostat.

Another grower (with lots of money) built a large table and used radiant floor plastic
tubing, covered with gravel and hooked to a propane water heater and circulating pump.
Might be more costly, but not if you figure cost per flat capacity of this vs. prop.
mats & thermostats.

It all depends on what scale you are and plan to grow to.  Or if you're planning on
diversifying into selling plant starts to use the capacity of a system beyond present
