I have a couple sets of acrylics that are middle of the road. Nothing really professional, just the Blick brand stuff in tubes and bottles and another set (I forget the name offhand). I also have a few different mediums to use with them, but I've always just used water for the most part, making them dry all the faster, which is what I hate about acrylics. I've just never had the feel for them like I do for watercolors or oils. I've only used them for a little bit of underpainting with oils and that's really it. I've not really "explored" them yet.
