Well, highest wattage I've ever hit with a mechanical was 45 watts at .4 ohms, never had the nerve to go any lower than that. That's a monster of a
vape already. How high are you looking to go, realistically, a 100 watt
mod will be able to power a coil pretty similar to a .2 ohm mechanical build, but unless that's the experience you are looking for, do you really need those extra 50 watts? Only you can really answer that.
One idea is to maybe wait for the 100W ones to come out and then
buy the 50W when the price drops as a consequence?
