Cool 40K Assassin models

I'm a tad underwhelmed by the 40K Vindicare and Culexus models. There are some alternatives out there - various Scout models for the Vindicare, mainly - though the Culexus is a bit set in stone as the head piece is rather visually distinctive. Too big and unwieldy-looking and a bit whack for me, but to each their own.

A Vindicare standing up to shoot is just a bit weird to me as a former platoon designated shooter myself, but I suppose. Gotta have uniform height for models for LOS gaming purposes and all that. Plus no-one wants a model that's lying down and covered in a ghillie suit. Callidus is fine, but for the paintjobs that people put on them imho - white skulls and emblems on a sneaky assassin? Sure, after the Polymorphine and all that, I suppose... Eversor - well, all bets are off there. Go crazy, maybe convert with an Arco-flagellant or something, though the base model looks swell enough.

But there's also older models to consider. Like, way old.

Some still available via Ebay at http://goo.gl/LEqqD (SFW, Ebay link).

"Cyborg Assassin" model.

Unreleased Culexus model.

Rogue Trader Assassin,
make the gun longer and there's your Vindicare.

Dark Elf Assassin counts as 40K DCA to me.

Incidentally, some Dark Elf fantasy dual-wielding models can look pretty nice. Unlike the official 40K Death Cult Assassin females in bikinis and high heels - lol what? So unless you're playing with jerks, I'd just substitute the dual-wielding Dark Elf.

Shadowblade, Dark Elf Assassin counts as 40K DCA to me.

Really, any mostly un-armoured model dual-wielding swords will do as far as I'm concerned. Slightly more reasonable and immersive than a girl in a bikini, high heels and two power swords. Your call, most people don't really care for things like reasonable realism in a fictional universe filled with magic and psykers and power armour and whatnot. But I do. RP, lore, fluff, immersion and all that. Less of a game and more of a story, to me, though I understand most people don't see it that way. Maybe I should stick to things like Mordheim and Necromunda, esp. due to the overwhelming fan-base focus on competitive WH 40K play. People doing "dice rolling technique" and nudging models forward to get in range, nit-picking template placements and rules and Win-At-All-Cost attitudes and all that. Plus I guess it's reasonable to get upset if you spend $1300 to field an army, get it all painted up and then get your butt kicked by some overgrown rules lawyer with poor or non-existent social skills. I'd rather not be in that environment.

But yeah, assassin models. Cool.
EDIT: Just toured a few gaming stores in San Diego. Turns out there's tons of ninja-looking appropriate-scale miniatures with dual-wielding daggers/swords from various manufacturers. Have a look around.
