In reply to Alan M:
Harvey's Ben Nevis and Glen Coe 1:40k map covers pretty much it all:

Saying that, Bridge of Orchy/Achaladair hills (which aren't covered in the aforementioned map) can be fun as well. Depending on the fitness, there's few options and a bit less of up-and-down compared to the Glen Coe hills. The walk-in can be a bit longer, just like Mamores.
I wouldn't dismiss Stob Ghabhar either, there seem to be few paths around as well for getting back.
Hitching a ride in Glen Coe has rarely been an issue. I even caught rides at night in winter with an ice axe strapped to the rucksack. I recently gave a ride to a fellow climber heading off Aonach Eagach as well. I must have hitched there over a dozen times before I got a car and the only time I couldn't get one was during an awful winter night in heavy traffic. Poor visibility, complete darkness and constant rain made it clear that walking back would be safer than standing on the road. Walked from Achaladair farm to Bridge of Orchy after a long day on the hills and I still think I didn't try hard enough to catch a ride.
There's too many options in Glen Coe and I don't think I have ever been on a hill (done all Glen Coe ones) that I didn't thoroughly enjoy. It's a lovely place.
