Cheap clone generally winds up meaning older design.
The standard advice for DL vapers these days is mesh. Specifically single strip single (very large) wick half circle wicked attys with some sort of compression or additional
juice system. I personally squonk a profile. Not sure if that is within budget though.
Another
device which is very much an RDL atty is a bigblock 454 v1. It is NOT a single coil atty. it’s a 4 coil vertical atty. it’s a bit of a PITA to coil and wick, but the flavor is outstanding and I got mine dirt cheap.
The hard bit is it does not squonk. The reason it’s cheap is it came out just as squonking was making a comeback so it sold poorly. It CAN be made to squonk but you literally have to drill out the center post to do it.
