If price was no object, I would get a few great devices to suit different purposes, as I like variety. A ProVari, GGTS, Silver Bullet, Touchwood, REO and Precise would be in my stable.
With no concern for cost, what I would put on them would be one of everything that interested me until I found what worked best for my vaping style. Price does not necessarily equate with satisfaction when it comes to getting satisfying vapor. For me it would probably be a combination of top and bottom feeding tanks and dripping attys.
