Hey! Cool to see another younger person in here! (I imagine most of the site to be old pros) I've just had my 23rd birthday and started gathering equipment around 20 or 19.
I think I got the same model hakko from frys for around $70. Just looked again, they're $100 now. I believe that was black friday / cyber monday price.
Hot Air rework stations are pretty useful too! I use mine for shrink wrapping, getting stickers off of things, and resoldering "broken" circuit boards. (Just a quick heating that is. No reballing (yet))
As others have mentioned, flux is really nice to have independent of your solder. Tricks include putting flux on your joint, putting solder on your pen, then just touching the solder pen to the joint and boom, soldered. Another is to add flux to your solder wick, this helps with the, uhm, suckability, of the wick... Personally I got some kester brand flux in a small pen applicator from All-Spec. I also got 2 nice rolls of 63/37 with kester flux. One with rosin flux and one with no clean flux. Also, a note on 63/37 solder is that it has a uniform melting (which also means solidification) point. This (supposedly) allows for better solder joints because both the tin and the lead will solidify at the same time.
Breadboard and jumper wires (stranded wire with solid core wires at the end) and jumper bridges (basically just solid core wire that is somewhat hardened to be less flexible) are really helpful for prototyping circuits.
A power supply is a good thing too. My first one I built out of an old PC power supply. Had an output for the 12, 5, and 3.3V rail.
Oh, oh, saturation, that's a better term than suckability. Another trick for solder wick is to cut off a small piece (inch or so) then hold it with tweezers. This way it heats up faster and the coil isn't acting as a heat sync. Tweezers are for not burning your fingers
A couple more advanced products you may want in the future are MCU programmers and an Oscilloscope.
An oscilloscope is the next thing on my list, I've gotten many recommendations for the Rigol DS1054z, supposed to be a really good starting scope packed with features for $400 :O
Oh yeah, I also got a Fluke 87V off ebay
MMmm Fluuuuke
Also do a good job with some Dettol on those ridges on equipment that gets full of that mysterious brown skank that collects on test gear and makes it sticky (or is that just me )
Uh, brown skank... You mean that stuff that also builds up on keyboards? Pretty sure that's your sheded skin cells dude. I pop all the keys off my keyboard and give them a wash every few months.
