I would go budget lvl 5.
I really don’t see any reason to go with a 5hammer if u start spending so much on gems.
If you really want a smooth experience with your priest before practorium, this is the set up Im using on my fresh rolled priest 3 (full spirit)
5Hammer +5 (5 red gem lvl 5)
cafrisun set +10 ( 2xyellow gems lvl 5 top and bottom, blue lvl 5 shoes)
didel tower shield (2x lvl 5 red gems)
2x gladiator bracelet
max petamion
3x budget headslot with patk or elemental damage ( you should look for 3 of those when they are undercut to easily level up your alts no matter what your main is, imo)
Before that the only switch I did were dagger at 75 and ledas shield at 120, I used abo set (2x rings) till gladiator and, lastly, a random necklace +10 till max peta
If you dont have any main char with gladiators, replace them with abo set rings or the +3 rings from main quest. If you dont have max peta stick with a +10 necklace (or consider abo ring+necklace and one +3 ring from main quest, if you miss both max peta and gladi)
Hands down this is the best exping gear out of there, imo at least
and trust me, auto attack priests are a blast to play in pve, with the right items and aspe + bless the damage output is pretty much WTF is that a level 40 fence3? 
note on valia: It’s the best hammer pre practorium for dex cleric thx to the 3x sockets (monk included) if you can find the aoe somewhere else (vubble+gladi) not a budget option for your monk, but very effective :3
