Havoc - When the Glittery SS first came out, I believe the starting price was about 5.5 mil. It should still be around that price range.

Xalax - Depends on how fast you can earn Neopoints. For example, if you earn Neopoints fast, you can skip the whole Frost Cannon stage and get a HH.

Blue Wolf - Option 4 (HH) sounds the best. I haven't been keeping an eye on prices of those lately, so I have no idea prices have changed lately. Try not to pay more than 2.2 for one though. Also, ever since Neopets changed the whole item defense, the Mask (which used to defend all fire), isn't as good as it used to be. Switching that out with the Flaming Oven Gloves would be a good idea, seeing how the Gloves are cheaper and defend more (additional 2 fire, 2 light). Consider getting a Downsize! as well (blocks 50% of an attack).

D-3000 - You may need a freezer, so getting a Black Frost Cannon or Rainbow Frost Cannon would be a good idea. If you're not big on the idea of the 20% freeze rate, consider getting a Honey Potion and/or take a look at the Sturdy Iron Lupe Boots (earth def) and the Iron Lupe Helm (light def) as additions to your set. Also, consider a Downsize! (3k or so now).
-------------------
snippet - Seeing how you have six multiple use weapons, you'll probably want to get rid of three or four of them. Consider dumping the Attack Fork first. Do you lab? If so, then dump the Fish Bone Bruce Sword. If not, then go ahead and keep it. The air and earth icons are a pretty nice combo.
Get a Honey Potion. It would be better if you sold the Tiki Amulet instead of the Frost Cannon if you do decide to sell one of the two.
Also, consider a Downsize!.
-------------
Mark - I would take Ghostkersword over the Sword of Skardsen. It tends to be harder to block than the SOS and, since you seem doubtful about spending big bucks on a weapon, is easier to resell than the SOS.

Hypno Helmet? I have about 450k right now..
