Go and have a search/read over the EEVBlog forum. Lots of reviews/posts/comments about various scopes.

Personally I have a PoScope, which I've had for years, and it does the job when I need it.
Having to use a laptop isn't ideal, although I did recently use it with my 8" tablet which was better.
If it was something I used more often, I would probably invest in a DSO, however the PoScope is handy in that it all sits in a small box with all it's leads, tucked on a shelf. Even a DSO would probably take up much more room.
