I've zeroed in on a Husqvarna Model 123L string trimmer strictly for home use, based on favorable reviews at www.Epinions.com, that are even better than Echo. This Husqvarna model is listed at www.Lowes.com as Model 123L with a price tag of $199.99. A similar looking model is listed at www.Sears.com as Mfr. Model No. 79100 with a price of $179.98. Not only is the Sears model less expensive, it also has a listed engine of 28cc whereas the same Husky at Lowes only says 24cc. Are they one and the same Husqvarna model but different engine ratings? Why would a higher displacement engine from the same manufacturer cost less? That doesn't make sense. Incidentally, the cheap Weedeater Featherlite FL25 I bought from Sears only lasted one season before the clutch broke. Can I take it back to them and get some trade-in value for it, since I've lost the receipt and the warranty card? Thanks for any help.
