If it were me, I would buy it for $100 to do the job right, then sell it to someone on the forum for their install to recoup some cost.
I bought all the correct tools when I did my cam install. Balancer tool, flywheel tool, lifter retaining rods, valve spring compressor and seal installer with the thought of selling them off after the job, but have since decided to hang on to them in case/when the next round of mods comes.
