SK Gear - on a budget

[FearlessTeapot]

I have around 5k to spend, and am looking at reasonably priced upgrades for a Troll SK. Currently level 20. I end up needing to solo a bit, so the gear is a bit of an issue. The economy on Red seems tough to crack - fewer items and little guide as to the value of things coming from a Blue perspective. If anyone can give me an idea of where to start, I'd be appreciative. I've already gotten a hold of a couple of 55HP rings.
