i looked into them last year
you would need a 2nd battery, even a 3rd if you are going to do a good FULL DAY
BUt when i worked it all out, 200 odd quid for the item, 50 for postage, then import tax, your about 300 quid ish
the same as a Sack truck, pump (in a box or not) and a battery
Yes sure, in the words of oasis, some may say, it looks better, BUT does the domestic homeowner care what it looks like ?? ?? ?? ?? as most know, i dont think they do *cue the abuse* my system looks better than yours, its more professional :
