Hi-
Thanks for the link, they have several:
∗Low Cost PCB Etching System(416ES)
<http://www.web-tronics.com/lowcospcbets.html> - no heater
∗∗LOW COST ETCHING SYSTEM w AGITATOR & HEATER (ET10)
<http://www.web-tronics.com/lowcosetsysw.html> -- looks like best one
∗∗Low Cost Etching Tank System w Agitator & Heater(12-700)
<http://www.web-tronics.com/lowcosettans.html> - similar to last
