I just replaced the front coils in my 84 GT350. This is the tool you need.

What're your guy's thoughts on this spring compressor? Worth the coin?

I once bought a set of HF compressors to do the struts on my wife's Neon, years ago (she has an Outback now). I never got around to doing them, because I just didn't feel safe even trying; ended up taking it to a shop.
But that seems really stupid to me to pay someone to do something that easy (if dangerous) that I could do myself. I'm willing to pay money for a tool if I believe I won't kill myself in the process of the work. I realize that when compressing springs nothing is 100 percent guaranteed, and one should do what they can to prevent injury in the event things go south suddenly, but every little bit helps, and it probably should start with the proper tool.
EDIT: Note - I realize this tool isn't for struts - but what would be a good (if expensive) tool for struts for home jobs, that would still be safe? I found this one, for instance:
