The 21.2 cc Echo SRM-225 two-stroke gas trimmer gets good reviews from owners and experts. Echo claims this model is the most fuel-efficient straight-shaft trimmer on the market, although unlike the Hitachi CG22EASSLP (*Est. $190) , it doesn't meet California's stricter emissions standards.
It weighs 12 pounds, with a cutting swath of 17 inches. It has a bump-feed spool head, and its starting system reduces starting effort by 30 percent, according to the Echo website. Users agree that this trimmer is powerful and easy to start, but some find it a bit heavy, and others say reloading the line is tricky.
Although the Echo SRM-225 is backed by a five-year warranty, some owners say getting warranty service is difficult. If you'll mainly be trimming a regularly maintained lawn rather than whacking tall weeds in the back-eighty, the less expensive Hitachi may be a better option. Alternatively, if you're prepared to spend more for a lighter and more powerful trimmer with almost no reliability complaints, consider the best-reviewed Husqvarna 223L (Est. $250) gas trimmer.

Review: ECHO 2-Cycle 21.2 cc Straight Shaft Gas Trimmer, Contributors to HomeDepot.com
This single-product review evaluates the Echo SRM-225i, a cousin to the SRM-225 that has a more advanced starter. Most of the pros and cons editors cite for this more expensive trimmer -- such as "Effective U-turn bump head" and "2-cycle reliability" -- can also be applied to the basic Echo SRM-225. Overall, the trimmer scores 8 out of 10 on performance and 7 out of 10 on value for the money.
Review: Echo SRM-225i Trimmer Review, Everett Snyder, July 23, 2010
Editors at Popular Mechanics compare the Echo SRM-225i to five other gas trimmers and give it top billing for its "nearly explosive power and torque." Despite its exceptional performance and "robust skidplate," editors do quibble with the trimmer' sliding lever rather than an automatic stop switch.
