After spending another 2 hours trying to get my 2 stroke Toro trimmer started (unsucessfully), I decided to take a leap of faith and buy a cordless trimmer.
Lot's of good reviews on the B&D GrassHog, so I bought one.
In a word - amazing.
Easy to assemble, light, and plenty powerful for 'standard' grass trimming and edging.
After (a long 9 hour) charging, the first battery lasted for about 25 minutes of non-stop work. Plenty to edge and trim my whole yard.
The self-feeding mechanism worked fairly well, but I did have to turn the unit over and manually feed out the line a couple of times when the GrassHog seemed to delay the self-advance feature.
The battery charging seems rather long, but with one extra, most people won't exhaust both during one trimming session IMO.
All in all - 5 stars. (saving me the frustration of never trying to start a seldom used 2 stroke gas trimmer is worth 3 stars just by itself).
Cordless or bust :)
