I have a Bosch Rotak rotary mower. Bought it a few years ago for my small lawn (30' x 8').
Had no problems with it, cuts grass well with adjustable height and grass collection works fine.
I bought it based on reviews and its relatively lightweight, because I have to carry it over my garden pond bridge.
If you want 'stripes' in your grass though, it may not suit you. Although the mower has a rear roller its not really heavy enough to give you stripes that last more than a day.
