I personally do not like using those death trap spring compressors. I bought a set from Matco once, used them a dozen times or so. Finally had it slip, and caught my arm in the spring when it sprung. I sold them on Craigslist for 40$.
I would take your struts off, and take them to a Midas or Monroe. You can normally bring cash and talk to a mechanic. Have them done by a professional, and spend 40$ or so.
It's not worth loosing an arm or eye. The wall mounted spring compressors are much better.
