From that list. Doggy is good. Digiflavor Siren is very popular, so is Skyline (I don't own them, so this is second hand information). Merlin? Not so sure it's a true MTL... there's a long thread somewhere, if you're interested. Nautilus is not an RTA (there's an RBA deck for it, but not worth it IMO). Taifuns and Hurricanes are older and I never really liked them--can't quite remember why.

Berserker is very tight, I hear. Check the thread Letitia linked above.
Another one you might like: Kayfun Prime--strict MTL, but only 2 ml capacity, unless you get an extension.
BTW, Phil's eagerly anticipated Ares looks a LOT like the Siren. Just saying.
