Greetings vaping Jedi, I have very little money and purchasing vape mods/tanks has always been a challenge for me. Originally, I was a heavy (pack of Camel lights a day) smoker since like 2001. When e-cigarettes originally came out, I bought a lot of those 'fake cigarette' looking devices (smoking everywhere, V2) and had some success as my craving for real cigarettes was suppressed. I switched to box mods about 3 or 4 years ago. I bought a Kanger Subox Mini 50W (for way too much at a local shop) and used it happily and successfully. Eventually, the box gave out due to all the leaking of juice into the internals (which is perfectly cool with me as it still saved me lots of money compared to cigarettes and not to mention the health benefits!). I bought another similar 50W box which I cannot remember the name of and it performed fine as well until it, too, gave out from all the juice leakage. By this point, I knew I needed to find a 50-75W box mod that was cheaper to save $$$ (since they always go out). I went into the local shop and asked the guy "what is your cheapest 50W variable voltage box mod" and he suggested an Aimidi Curve V4 mini. I was stunned when he rang up the sale. It was soo cheap (I want to say like $17.50). This worked great for about 1 year.. then gave out from juice leakage. When I went back to that same store and asked if they still sold the Aimidi Curve V4 Minis, he looked at me like I was from another planet. Their cheapest setup did not allow for changing the voltage (just a single button) and was outrageously overpriced. Another store in the area also had nothing affordable that fit those specifications. My question to you: Is there a good trustworthy online store that sells 50-75W variable voltage box mods (I don't care if they're not the best or if they look 'ugly') that use a 510 connection screw preferably not over $40. The cheaper the better (and I know some are going to say you 'get what you pay for'.... please just save it for someone whos not broke as a joke and nearly homeless). My existing tank is a Motofo subtank and I'd like to be able to use it. I already have batteries. Thank you in advance!!!
