Best Bang for your buck items

[Pyrocat]

Fungi Tunic (the regen completely changes the solo capability and survivability/efficiency of many classes)
Brell's Keg Popper + Tola robe (int caster melee combo, works well into early 20s)
Gatorscale Sleeves (150p for +int and +hp on a slot with crappy options until planar/velious armor quest gear? yes please)
Golden Efreeti Boots (again, you won't find an upgrade for these until very late game)
Jboots
Hand Made Backpacks
Leatherfoot Raider Cap (get out of jail free card, only costs 90p to recharge)
Crystalline Short Sword (one of the cheapest 1 handers for main or offhand that has a 1.0 ratio)
Guardian Mace (even better than CSS for slightly cheaper, but bard/pally only)
Noctivagant Blade + Atramentous shield (ultimate twink-on-a-budget combo for newbie SKs)
Poison Wind Censor (great ratio, the negative proc that makes it cheap doesn't start until lvl 50)

Rogues and Monks have a ton of weapons that are rogue/monk only with amazing ratios that go for incredibly cheap because they are dropped in areas where people commonly level or are rogue/monk only. Trak tooth, wu's staff, peacebringer .etc
