I want to get a garden edger to help me with my landscaping. The soil here is rocky and clay based so it will have to be one with good power. If it trenched too, that would be a bonus, but I'd rather have a good single-use tool than an adequate compromise. Gas powered is probably best, but I'll consider whatever does a good job and makes a nice straight line.

PS I live in a smaller town and no one rents them here.
