alakazam

This 100%.
The difference between that and a perfect Alakazam at level 30 is less than 70 CP. 70 CP isn't worth waiting months for. Especially on an attacker where CP doesn't matter as much.
Edit: This only applies if you will actually use him. If you aren't going to use him, obviously don't power him (or any future Alakazam) up.
I agree with redeyejedi. You are lucky to have the best moveset on the first try. I just got my alakazam about a month ago. Abra is rare in my area and i had to walk with my good iv abra to get the candies needed to evolve it to alakazam. It was a long wait and luckily i also got the best moveset on the first try. I dont use him much in gyms but i still power him up. Highest attack stat in gen 1 next to mewtwo and he is potion efficient.
You got the best move set, which is more than half the battle. The IV's are good. Now the only questions you should ask is in what capacity and with what frequency will you use him? If he's just an occasional niche attacker, I'd leave him where he is and spend the dust elsewhere. If you think he'll be a regular in your attacking team, go for it.
Either way, test him out a few times first. His low stamina regardless of IV's requires you to be a decent dodger. If that's not your style, then it might not be worth the effort.
thanks guys for all ur replies! i think this will be my regular attacker for at least some time since i still dont have a dragonite, ill try it out in a few gyms first but i can definitely see myself powering it up! abras are rare and all ive seen are ones with lowest iv apprasial until this one came along, so i do consider myself lucky haha :) (not so much with a lot of my other evolutions i must say)
