In the market for a mini excavator.. Which one?

[TopnotchER]

Hey guys I'm going to start looking for a nice used mini excavator. I would like to hear from some people that have Actual experience with some.. I have a nice sized lawn and landscaping business and I was wondering what would be a good all around size for me to do a lot of landscaping and whatever I may need to do.. Don't want anything tiny with no strength or power.. Please people that have experience fill me in... Thanks
