It's a doable job -- I've had mine in and out several times and I'm not that experienced. You only need a spring compressor to install the springs, not take them out. Follow the service manual. Eastwood and other companies sell a quality product. Stay away from the "Made in China" brands. The spring is very dangerous when compressed.
The major PITA to me was getting it compressed enough so that the lower A-arm can be positioned correctly and getting the spring oriented properly in the pocket. More than once I had to start over because one of the arms of the compressor got stuck between the spring and the pocket when I loosened it!
