Gil, Matt and Jennie, et al Original boots lasted for decades - I am still using some driveshafts that have their original boots on 'em. A new boot should last for years. I have had back luck replacing boots without dismantling the front trunion; it seems that, by forcing the boot thru the housing past the cross-piece, that the new boot might get stressed / scarred / gashed in some way or other. Two boots installed that way failed pretty quick. I now send out the driveshaft to my local driveshaft shop, which has the special tools needed to press out the cross-piece, install the new boot, and reinstall the cross-piece, having it perfectly centered once again. Having done it that way, I have not experienced a single boot failure since. I was not aware that there were various quality rubber boots...
