I am about to order a quickie 32 that i've heard so much about. This will be my back yard mower not primary. Any suggestions? Should I get the step saver...doesn't seem neccessary as it will be used in back yards only. Motor..is 13.5 briggs enough? I'm not a briggs fan, but I will not be putting many hours on it, so I don't think it will crap out too fast on me, opinions? And is pull starting these machines okay, or should I go electric? And, does this mean I can get rid of my 21" or should I keep it for back up?
