+1 for the PD Oilers, with one condition. the system seems to work very well and mine has been reliable and convenient ........ but the integrated ones (i.e. not the mini with a separate reservoir) are a total PITA to refill, what a stupid pea brained idea that was. I see they now do a clear version so at least you can see what's in there (if you don't have it tucked away out of sight), but having to use a syringe and dip-tube gubbins to fill and check the level is not user friendly. Otherwise yes I'd recommend them. The mini with separate bottle is the way to go if you can fit it somewhere.
