I have rented from both. Charles was at the airport the first year I rented from them, which was handy. The second year I went with Trees as Charles was not at the airport anymore. Both were great for what I needed - just to check in at home a few times a week while I was away. This year I went back to Charles as he posts on this bulletin board and I enjoy his postings and he's a very nice man. I think it's what all what you are looking for...prices, minutes, etc. For me, Charles fit the bill. See you in two weeks Charles!
