I would not use a wealth as it may lower your chances. Defenders are non tradable so there value is 0 gp. The wealth helps your chances with high priced items like dragon so therefore it would not help but make things worse.
FRAPS is another good one as it will record in higher detail than hypercam or camtasia. It's free but has a bigger file size. If you buy PC Gamer then its on the disc thats with it every issue.
Iron Plate, red dragonhide chaps and vambs. They give good defense and a range attack bonus, and even if you are using melee they are still good to use.
You could always get hypercam and make a small video on your bank, like a minute long i mean. Otherwise just use paint if you don't want to make a video.
Steel Plates are a not bad way as you only lose 100 per alch if you buy for 1k ea. Green Dragonhide Bodies arent bad as you can actually make profit on them. If you can't get a lot of these then I would suggest buying steel or mithril items and alching them.
