Ok so I'm about to get a sigelei 150w and I'm trying to figure out if I should get a RDA or RBA. I really like the RBA's because most of them have tanks and that seems really convenient, but I also hear alot of problems about leaking. RDA's are cool too I just don't think I would like having to add juice all the time. I just want something that will chuck out some nice clouds and taste good and fairly easy to build coils. I'm currently vaping a MVP 20W with a aspire nautilus but I'm looking for a huge upgrade. Please help, any advice/comments/info would be great P.S. Also nothing with a price tag over 50$ preferably..
