I prefer carto tanks as well. IBTanked are my favorite. But Fluid Flask (they are promising to do a glass tube) and Loki Labs SS1 both are filled by removing the top cap. They both work good as well.
Right now I only have ProVari's. And although I never tried any VW device, I don't feel like I missed anything. After about 3 months of vaping I replaced my Ego Twists with a ProVari because, like the OP, I didn't want to mess around with a bunch of stuff that didn't last long or work well. For a 2nd device, I got a ProVari mini. I have no regrets. Between the 2, I have something appropriate for all situations.
The only thing I really want is a mech to go with my rba.
