good thermostat and heaters?

can anyone recommend a good cheap thermostat and small heater? i need two, one for a 15sq ft space and one for a 30 sq ft space ideally liked to the same thermostat.

also does anybody rate odorsoks filters? theyre really small but ive been told theyre just as good as a usual large filter.

I'm about to run my odorsok on a flower room for the first time. I have 2 flower rooms and 2 odorsoks. I will let ya know.

I like the oil-filled potable radiators you can get at any hardware or department store this time of year. They have a built-in thermostat but you may want a second for more precision.

I don't like the electric fan style space heaters because I have seen too many people dry out their plants using those things. If you use one, point it AWAY from the plants.

thanks stinky, i reckon i'll end up getting an odorsok they seem like a good buy, hopefully i'll be able to afford the oil ones, mind you if i did get the fan heaters id have to buy a thermostat for them anyways which'd probably cost as much as the oil ones anyway...
