Fortunately, I saved the graduated cylinders, beakers, and pricey glass syringes (the plastic ones lost their markings WAY too early). Any chance that my 3 year old flavorings are still any good? I should probably toss those. And I bought loads of em..
You can avoid losing the markings on plastic ones simply by putting a strip of tape on them -- they last about a month before they don't work well anymore. If the flavors are in glass bottles, then no problems. If they're in plastic... they may have acquired the taste of plastic, depending on the flavor itself and the type of plastic; soft plastics (LDPE and similar) seem to be the worst, and some flavors react badly with plastics of different types.
I don't use any of that other crap; I use plastic syringes with markings taped, and I mix straight into the glass bottle the juice is going to stay in -- no wastage with ejuice stuck to the sides of the cylinders. The only other tool I sometimes use are some small funnels; at Hobby Lobby I found some very tiny ones that are used for "sand art"; they're particularly useful for pouring my 120ml bottles of nicotine into 30ml glass bottles for freezer storage; 100mg nicotine is not a good substance to make a mess with.

Hobby Lobby also has glass droppers with pointy ends, much better than the "bulb" type droppers that come in some glass bottles.
