I'm also a cheap 0.01 scale user - once I'd realised that all my syringes were taking up too much time, and making too much mess, I bought the first set I found online for under a tenner and they've been with me now for about 8 months without issue. I usually mix in batches of 300 ml and it takes me about 15 mins start to finish. I also occasionally will try new flavors, but what I tend to do is add a few drops to my ADV and then decide what percentage to add to my next mix, and so far I haven't thrown a batch away - some have steeped for a while before they're to my taste, but all have vaped satisfactorily. I may have simple tastes, but I know what I like.
