haven't bought this yet, but planning to. I am a big erlkonigin fan and have 5. I feel the same obviously about the erlk, it's simple, small, easily set up, and looks great. Have you tried the km3? Although not as short, it is however a very awesome tank and every bit as good as the erlk. Although it's only 19mm, it is tall but besides that, it's awesome.I'll be watching this thread closely, this By-KA looks interesting.
I would love to find another tank as good as the Erlkonigin. Very few parts to clean and assemble, fantastic flavor and easy fill - and absolutely NO dry hits or leaking. I've tried many - Mark Bugs Gem, Calix, Phenomenon Lite, Russian 91%, KFL+ - and they all have one problem or another. Maybe this one will match the Erl K?
