Many thanks for all the advice. Avo,I think I may need a bit more experience before trying the wagtail.Ive watched a video and it looks as if it takes a bit of getting used to. JP,read the link to Ettore one you use.It says that it swivels.Does this mean it 'steers' if you twist the handle when using.Sorry for ignorance but,like I said, I am still learning and the best advice is from those that have 'been there'.Thanks.Graham
