I have an MS211 and love it. It's light and smooth running. The 250 gives you a bit more power for the trade-off of a little more weight, but it may be a better choice for your stated needs. The Easy-2-Start option is available for either one, and is probably a good choice. The best thing would be to find a place to try them out, or at least handle them for a while. It really depends on whether you care more about weight/vibration or power.
