Remember, there's no hard evidence that 2 dex = 1 acc. If you re-read the SE interview frequently posted, you'll notice they do say 2 vit = 1 def and 2 str = 1 atk, but not 2 dex = 1 acc or 2 agi = 1 eva. They state that it's better to directly raise acc than via dex, so it's not a 1-to-1 relationship... and if it were 2-to-1 like vit/str, they would've just said that. So likely, it takes at -least- 3 dex to get a point of acc by your own stats... possibly more.
So yes, the bracelets are quite awesome... I like to swap them and a swordbelt+1 in while sneak-attacking, since it's a guaranteed critical hit, I'm adding 7 STR and 12 attack to the cause. Owch X) I don't leave them on though, -4 agi? Yikes...
Onward, some other equipment thoughts up to 70... A bit of this is easily attainable/cheap, some of it is kind of expensive, and a lot of it is expensive or difficult to obtain. Still, it's a sample of items you should keep an eye our for, in my opinion...
Level 43 Swordbelt/Swordbelt+1, great DD until Life Belt
Level 58 Master Belt, a good option if you don't need as much acc as life belt, but swordbelt's 0 acc is too little.
Level 55 Federation Army Mantle, a great tank item, requires rank 6
Level 55 Royal Army Mantle, DD, requires rank 6
Level 60 Behemoth Mantle, tank
Level 60 Byrnie, awesome armor, huge boost to damage and doesn't gimp you as a tank like haubergeon does. You can even put Defender on and still hit hard.
Level 69 Hauberk, DD, just trade in your haubergeon
Level 1 Cassie's Earring, tank or DD, I hope you're rich!
Level 30 Pilferer's Earring, /thf DD sub. Who'd argue with an extra 2 dex?
Level 30 Genin Earring, /nin tank sub. An extra +1 agi over a drone earring.
Level 58 Assault Earring, pure DD.
Level 70 Fenrir's Earring, DD, good luck getting this or...
Level 70 Pixie Earring, DD, that.
Level 30 Archer's Ring, DD luxury item, if you plan on getting sniper's later...
