IG/Inquisition stuff needed

Hey, I'm wondering who out there has any guard/Inquisition models or bits?

Specifically, my Guard need plasma. I noticed at the den a pack of meltaguns for sale, but so far the only way I've seen of getting plasma guns is to buy the 'special weapons pack', but thats like $18 for a meltagun and a plasmagun, and I'm not so sure I'd even use the melta.
I'm also looking around for prices on any vehicles (Lemans, Chimeras, Sentinels, etc), though I'm not sure if/what I want in that category yet..

Finally, I need to expand my Inquisitor Lord's retinue of henchmen(Read as: actually get him some so I can stop proxying it). They're hard to find. I'm wondering if anybody has any of the following: Crusaders, Chirurgeons, Sages, Gun Servitors, or Acolytes.

Also, a question about the acolytes for any who may know: Since they have such a wide variety of wargear available to them, how do you model them with the appropriate wargear? I mean you could have an acolyte with power armour and a bolter (use a marine?); carapace armour and a storm bolter; Power sword, shotgun, and Melta bombs; Plasma Pistol; Artificer Armour; .. etc etc.. Do they sell different figs, or do you just pick up bits and try to mod it yourself? (I'm specifically questionable about the armour, as they can be wearing carapace, power, or artificer.)

I have a few extra plasma guns. Darren can order blisters of them too, just like the meltas.

ooh, didn't know that. I keep thinking "WYSIWYG" applies to purchase availability, too *L*
