I decided that it was time to buy a 4 stroke string trimmer this week. I found that the Honda 4 stroke trimmer is near impossible to find for sale in the southeast and is not available for shipping when web shopping. The Stihl is 4 stroke but requires a 50 to 1 gas oil mix....forget that! The Robin sounded the best option from multiple sources including this forum. Here is what I found out about the Robin: Apparently Suburu makes the powerplant for the ROBIN GAS TRIMMER WEEDEATER BH2500 4-CYCLE. Here is Suburu's discussion of the engine: http://www.robinamerica.com/engines/detail.lasso?mdl=EH025# Here is Robin's site(pretty lame I must say): http://www.robinoutdoorpower.com/pro-trimmers.htm Here is where I bought the unit for $240: http://cgi.ebay.com/ws/eBayISAPI.dl...from=R8&satitle=160096147486&category0=&fvi=1 Hopefully this helps other in their due diligence regarding another 4 stroke trimmer option. I will report my trimmer experience with the BH2500 as soon as I can.
