Drum brake tool set
The last time that I removed / reinstalled my centerstand, I just used the tools in my el-cheapo harbor freight drum brake tool set. Remember that the puller is only half of the problem. Getting the spring back on is a pain too, and a tool like in the drum brake set works nice. (I'm talking about the shaft with a notch in the end that fits over the spring post.)
I'm also very thankful that all of my vehicles (Sienna, Silverado, Trans-Am) feature four wheel disc brakes. Boy do I hate working on drum brakes....
