I am in need of a new parts washer for the shop. Really would like to have a spray wash cabinet, but thats not in the budget yet. I have been using an el cheapo 20 gallon solvent based washer, would like to go a little bit bigger, but am having trouble deciding between aqueous, and the solvent based. I have only used an aqueous based one a few times, and liked it. Dont know how much the detergent costs, and I presume they have filters that need serviced as well. Solvent is rather expensive, and I have replaced my pump twice now in mine. So what do you all think, help me decide
