I haven't looked into buying a rack, so I can't tell you if the priced are fair. However, I have been buying the ultra therm heaters from him, they are not flex watt, although they do look exactly the same. The ultra therms are more energy efficient, less wattage and they also do not get as hot as flex watt. I guess because the ultra therms are more money than flex watt, that could make the prices go up. Hopefully I helped some, sorry I couldn't of been more help.
