Jaundiced Bone Bracer - to buy or not to buy?

[Polixa]

I just got to L49, mostly via solo and casual, unguilded. Took about 6 months, as an indication of my playing time/skill.

I have a dream of one day having enough money to buy a fungi tunic, and so far I have got up to about 14k, which I see is in the ballpark to buy a JBB (according to the wiki page).

Opinions requested please, should I:

1. Keep saving up the other 25k for a fungi, or
2. Spend my wad on JBB and start saving for the fungi from scratch?

And take into account I have zero expectation of raid gear or epic in the foreseeable future. I already bought a haste item, HP jewelry and a decent 2HB weapon, and the rest is made up of gear I collected along the way.

TL;DR
This is another way of asking if the JBB is "worth it" but I thought I would throw some context around my question. Thanks for any advice.
