I have a line on a 24v xd9000 from a fellow mudder. I know the 8724 is the end all be all for 40's but is it worth the extra coin? The 8724's are averaging around $1800 to $2000 + new and while if you wait around and search you can get used ones for a reasonable price it's hard to find a 24v model. I can get a lightly used (or so I'm told, "2 pulls") 24v xd9000 for less than half of what a new 8724 is going for, should I pull the trigger or wait until my budget allows the 8724-50?
