I recommend using these over the grandmaster's gloves. The difference between the two is:
19 Ac, 1 dex, 1 sta, 1 wis, 1 agi, 15 hp, 15 mana, 15 endurance
On my server (Bristlebane) you can pick up these gloves for about 500pp, and the GM ones for around 30-40k (though there's none for sale at all recently). Of the differences in stats, only the AC looks useful to me, and certainly not 30k useful!
If you want to spend a little more though, then invest in a GM aug over the master one. For these the difference in price is less at 30k for a GM aug, and 20k for a master aug. But the stat difference is significant:
2 str, 2 dex, 2 sta, 1 cha, 2 wis, 2 int, 2 agi, 1 fire resist, 1 disease resist, 1 cold resist, 1 magic resist, 1 poison resist, 20 hp, 20 mana, 20 endurance, 10 Attack, 1 Regeneration.
