Get yourself some 0.3mm/28AWG A1 Kanthal Wire or 0.4mm Ribbon - It'll bring the resistance down to a more Mech-Friendly 1.0ish ohm. So long as your batteries are comfortable with it, you'll see a huge difference in warmth, flavour and vapour production.
As for VW devices, I've been using my VTR as a "chuck in the car" device - bombproof build quality, decent range (no idea on the official specs, but mine comfortably powers a 0.6ohm dual coiled dripper at 12W, or my 1.7ohm single coil, rope wick Kraken at 15W). I've cut the atty ring off and bored it out slightly so a tall 22mm atty fits without the extension tube. 2nd hand they can be Picked up for around £40-50
I hear the MVP is of similar quality for less money, but more restricted range for coil resistance.
Otherwise, you're looking at £120+ for the Dicodes Dani or similar, but for that money, I'd be looking at a DNA30 box mod by StiG or SoulVaperBaby.
