I use a crappy clothes iron I bought at Walmart for $6. I set it between synthetics and silk, and it melts the wax. I'm quite sure that $40 irons would work even better, just like a brand new Subaru would drive better than my 20 year old one, but I find no difficulty in the use of the iron I have, just as I find no difficulty driving to the mountain in my old beater car.
If one desires luxury, one can have it by paying for it, but for many, it adds little for the amount it costs.
I find little advantage waxing skis until temps are approaching melting temps. Base material slides well on snow, if it didn't, ski manufacturers wouldn't use it. Yes, waxing will make skis faster, but really only by about 1%, structure does more to decrease glide reducing friction.
