i have a used zoomed 500r thermostat. i used it for 2 weeks while i waited for my johnson control thermostat. i have all the packaging and instructions, even the tie wraps for the cables. if you need a cheap thermostat, or just a temp on this is a nice one to get. $25 plus shipping (i assume $9). i have paypal, or will take money orders.
i also have a 20-30 gal zoomed UTH brand new still in packaging. will sell it with the thermostat for $7. (will ship in same box to save $)
