Unless you're loaded, that list doesn't look like something a recent college graduate can amass and still have money for food.Analog oscilloscopes can easily see fast PWM signals, digitals ones are just smaller and more friendly.If you mostly just need to see PWM (or digital signals), get a logic analyzer. They are alot cheaper.For tools, can't forget the essentials like pliers, strippers, wire-cutters.You might also need a machine mill, it might even be more useful than a lathe.
So far it seems most people are pushing for an analog oscilloscope. For this I've found this model so far:http://www.amazon.com/Instek-GOS620-MHz-Analog-Oscilloscope/dp/B0007R8ZCG/ref=pd_bbs_sr_5?ie=UTF8&s=industrial&qid=1228048468&sr=8-5I've used this exact model in some labs before - it sucks sketching waveforms that are below a certain speed though. USB models tend to be slow from the version I've seen and not worth the price overall. Also a tool dedicated solely to that purpose (ie a real oscilloscope versus a computer trying to be one) tends to be better anyway.As for soldering iron - you'll see that I selected a 100 watt variable temperature soldering iron that's pretty good quality. Unless suggestions for that get better, then that's the one in the running right now.I've also updated the handtools section.As a side note - what's a hemostat?
How accurate do you need your power supply be? My powersupply is just a modified 350W ATX PSU, it provides 12V@18A, 5V@35A, 3.3V@28A, -12V@.3A, and -5V@.8A. It works great with everything I need. And it is alot more powerful than an affordable commercial one. And, it was free because I just scavenged it out of an old computer.
links for building your own benchtop power supply from an ATX computer power supply are allover the web.

Is the quality decent? Is the cost versus the time spent making the power supply worth buying the power supply or making one.
I also really like the numerical displays on digital scopes, though I worked with one analog scope that also displayed stuff like peak-to-peak voltage, cursor position etc on the screen. It was pretty cool (I think it was a tektronic)
