Welcome aboard. Where abouts in NEO are you? Fun fun fun with the snow here in Geneva!
Cleaning and refilling cartos seems a lot harder than it really is. I sort of compare it with taking the training wheels off your first bike.
I'm still new enough to remember feeling like "what the hell am I getting myself into!" when I did it the first time. If I can fill up a carto before my first cup of coffee in the morning than anyone can do it
As for juices, look around at a few different place and try a bunch of sample packages that the vendors offer. What I think is the bees knees might taste like something out of the litter box to you and vice versa. Good thing about the samples is that if it tastes like sweat you're not out a chunk of change and have 28mls of it sitting around collecting dust.
If you or your husband are decent at a hands on stuff a good thing to try might be making a puck mod. Although I suggest ordering a 510 connector from MadVapes so it will be compatible with most cartos out there. Under $20 in parts, uses AA rechargeable batteries that can be gotten at Wal-Mart (same as my digital camera takes). The thing is not pretty but it's functional and good as a back up unit, as well as something to use if your "regular PV" batteries need charging.
