Anyone who doesn't have a rental policy on your insurance, I would highly reccomend it. We had an little accident with our truck and our policy covered a replacement unit for the time the truck was in the shop or they would pay for lost income. Well worth the 300$ a year extra!!!!
If you're only doing a few stumps a week or month and have a mini, I would check out the 38 special. It's so easy to have with you if you're already there with the mini!
I think Daniel was selling his RG50 on here not that long ago.
