As far as the bubbler goes, I was a little leery of sticking the PD into it. It is pretty small and all. After a few tries I got a good method that is now second nature. I basically load the stem, stick on the PD, wait a couple minutes. Then I pick up the PD and place the stem between my middle fingers as I hold the PD on the Bub- which I hold in the other hand. Sounds weird when I write it, but works great.
Bubble, bubble, bubble....woosh!
I'd say go for it. It was way more than I wanted to spend, but it really is pretty. It's so nice my wife lets me keep it in the bedroom!
F-ing inlines. I had stopped thinking about them, but now that I saw that picture... damn!
