I am not a DEK user but have some knowledge of the ELA to share. The ELA has some structural differences with the Horizon and Infinity models. It is DEK's low-end automatic printer (a cost-reduced version of the Horizon model)and is manufactured in China. The ELA has an open-chase frame design (structure that holds the stencil), whereas the Horizon & Infinity have a closed-chase frame. DEK offers three levels of camera systems, green - grey & gold I believe, and the ELA has the lowest end standard. Concerns with the ELA should be long term durability considering the contstruction and its ability to print 12Mil repeatably. If these are concerns you should consider the Horizon model. Check the accuracy and repeatability specs on the ELA vs. the Horizon. I suggest you contact DEK's applications engineers and I'm sure they'll be able to explain the differences in great detail.
