I am in the market for my very first gas string trimmer. My first purchase was a "Black & Decker Grass Hog" cordless trimmer with edger. It would only stay charged for about 20 minutes (even less when I used the edger). It lasted about two years so I decided to buy a "Black & Decker" electric, and the edger clip broke off on the first day. I took it back and bought a "Homelite" split boom gas trimmer which was a display model at the "Home Depot". It was discounted from $99 to $69 but it did not work when I got it home so I took it back. I like the idea of having a split boom so I can attach an edger to it. Yesterday I went to a local lawn equipment store and the salesman showed me a couple of his "Stihl" trimmers but he did not have a split boom but he showed me a straight shaft split boom in a catalog listed for $279 plus $90 for the edger attachment. $370 is more than I am willing or even capable of spending since I am on a budget. Sears has a Craftsman 34cc, 4 cycle split boom for $170 plus $54 for the edger attachment, and for another $35 I can purchase a "3 year In-Shop Repair Protection Plan". That would be a total of about $260. This is the absolute most that I am willing to spend. I like the idea of not having to use the gas/oil mix since this one is a 4 cycle. I know that there will be times when I am not at home and either my wife or teenage son will want to give it a try. I would just hate to know that they put straight gas in a 2 cycle engine. I would rather eliminate that factor from the start. The three year warranty would offer me some peace of mind. Any thoughts on this model (#79612)? My yard is less than half an acre so it will not be used that much (maybe once every week or two in the summer months). Thank you!
