After some rethinking, I've got a MA957 regulator/solenoid/needle valve combo and SMS122 pH controller that I never really got around to using and the new plan doesn't require them. I'd rather someone here find a use for them than have to do the eBay bit. I was thinking ~150$ for both which would include the shipping but would entertain reasonable offers for one or both. Both are new and never used.
