SX Mini is the highest end I would go to. I mean it's quite affordable and the quality is top notch!
Yeah, the build quality on Yihi mods are pretty much top notch. Most importantly, Yihi being Yihi does the best wiring jobs for their SX chips. A lot of HEM modders imo are just out there trying to make a quick buck or two and poor grounding or wiring job leaves a lot to be desired. Horrible voltage drops causes the low battery voltage protection to kick in and that imo, sucks bad.
I'm in this dutch vaping group and we got a few individuals who are into this. One of them bought some kind of exotic mod for around 500+ euro's. I forgot the name of the mod couldn't care less since it doesn't shoot lasers or has a build in porn library or whatever over the top piece of technology, i was mainly shocked about the price really.
Waste of money IMO. But hey! It ain't my money, so again, don't care
Scarily enough, 500 Euros is on the really low spectrum of pricing as far as High End Mods go. The flip/2nd hand market or the raffle markets are where things get serious. Gepettos, S.L.A.G's, SLGT's, Lochness, CC Alpha's, CC Gamma's, etc... have all seen much higher prices from $4000 USD up to $10,000 USD or more.
To be honest, it's a debatable issue whether HEM's are a waste of money because like any other hobbies (such as watch collecting, car collecting, knife collecting, etc etc....) acts of compulsive spending on material goods put u right into the hobbyist category.
The important issue to take note is that as long as we spend within our means and gain some form of satisfaction out of whatever hobby we might have, everything should be fine.
