Do you have or know someone with a solder iron or a good butane torch? Or a b&m might have one you could borrow, depending on how well you know em, lol. Point being you can get a fat daddy 510 or similar for about $5-10, it's a very, very easy solder (first time I ever used a solder iron was doing this on a regulated mod and it worked great, there are YouTube vids that show how-to) - might keep you from having to drop a ton of cash on a new mod. Just speaking from the POV of a broke single mom who's wanted a Sigelei for about 6 months, I'd hate to see it hit the junk heap over such an easy fix!
