Thank you Tom. As always a very detailed and thoughtful answer.
Yeah, I did contact Trem about this question too but it was Friday night and I don't think he's around till Monday so I thought I'd get a jump on the answer from an actual customer of the product so I could put my order in sooner. I'm pretty sure it's gonna be the Silvergen and not the Puppy mainly because of the variable PPM dial and the magnetic stirrer. Prior to this decision, my last resort was to get a thermal stirrer from the Silver Puppy guy to use with my DIY setup and I wasn't happy with the results so I'm pretty sure I'm gonna spring for the Silvergen.
