Still using my PD from 2009, but this week the heating core has dropped some more, so it wobbles around much more. The unit has actually gone cold on me a few times. I'm up to 3 retaining clips now, is there a max? I think I have one more laying around, but it may be time to consider a replacement. I'd want another simple log type, so it looks like an UD may be a good choice. Trying to read through this site and find the differences, good and bad, between the two.
I think my favorite thing about the PD is that I use it once daily, a stem can last two days, and I can make an 1/8th last a solid 6 months. I'd like to maintain that efficiency.
