I am looking at purchasing a Shindaiwa grass trimmer. The models I am looking at are the t230 and the t2500 (new 4stroke/2stroke hybrid). The t230 is $430 Canadian (approx $280 U.S.) while the t2500 is on sale for $485 Canadian (approx $320 U.S.). the t2500 is a bit heavier but supposedly consumes a lot less fuel. However, is it true that it also requires valve adjustments and other maintenance that the t230 does not? Also, I have heard that the t2500 is hard to start. Any feedback would be appreciated. Thanks in advance.
