Where in the world are you?
How can anyone answer that question without knowing where you are?
My apologies - I'm in the US - More specifically, Virginia.
I have been getting my tips from TEquipment. I use them a filler on my order to get me to the point of free shipping.
I avoid ebay and amazon since I have a good chance at getting fake tips while paying for the genuine article. I used fake tips before on a fake Hakko 936 and, in my opinion, the genuine Hakko tips last longer and solder better.

Unfortunately, I got this soldering station from e-Bay. I keep hearing the "reputable source" but how do I know if they're a reputable source? Second, from what I've gotten, I can not just go and buy any old random tip as a replacement for this, it must be that specific model's tip. Correct? Also, as I've said before, I went looking for tips for this model, but I really struggled to find much of anything that's not from ebay or Amazon.
EDIT: I managed to find the actual Hakko website which did provide the tips (the other one I looked at, hakko.com didn't have tips)
http://www.hakkousa.com/detail.asp?CID=&PID=4800&Page=5 - out of these tips, which would be the most useful? I realize chisel tips are the most useful, and I already have a chisel tip, but what else should I have in stock with me? I'm on a budget, so I'm trying to get the bare essentials first - I'll build up from there once I've gotten the essentials.
EDIT 2: Nevermind, didn't see Nanofrog's very helpful post! Thanks a bunch Nanofrog!!!!
