Which Mascara?

I have for many years been looking for a suitable Mascara. One which does not look gloggy (if that's a word!) one which your makes your eyelashes curl, separate and longer than they really are. I have tried many, cheap and expensive ones but to no avail. I may, of course, be too fussy (I have been known to be before) but that's all I want a good Mascara - not too much to ask is it? Any suggestions please? - thank you .
