Hey guys, I've been running into problem after problem with my Lavatube, and Im sending it in for store credit and waiting for the stainless steel one in hopes for better build quality. Problem is that I need to send the mod in this week in order to get the store credit, and I regrettably sold my backups because I needed the money. I need recommendations for a cheap 510 mod which either uses 18350 batteries or is rechargeable. Would really like the cost to be under $20 as well. I have a shipment of 3.0 ohm boges on the way, and one LR306 atty. Someone please shoot me some recommendations. Would a passthough be the way to go?
