http://www.stihlusa.com/trimmers/FS100RX.html http://www.echo-usa.com/product.asp?Model=SRM-265T&Category=TRIMMER I would like to here from anyone that has ran both. Yes I did a search and found some good info., but come on it's Dec., lets talk about them. We have a couple of 265T's and we like them. We also have Stihl blowers and and edgers and we like them. Looking at the specs, the 100Rx is lighter and has more power than the 265T. We need to get a couple of more trimmers before spring. I may buy a 100RX and try it out. The 4 mix sure is easy to start.
