i;ve just taken the plunge and spent £409 on a manual hannah hose cart from Gardiners...
it's one about because at current rate my guys destroy a hose cart every 6 months or so... and before it's destroyed it'll be rattling about and causing them problems. hopefully with the Hannay we can get at least 5 years out of it in good working order. Alex estimated we should get around 15 years (though not guaranteed of course).
if it works well for 6 years we will have saved a little money, and a lot of hassle...
