:dizzy2:
hi all, i imagine this has been asked to death so ill apoligise beforehand,
im a gas registered plumber mainly i do installation & a little servicing it wouldnt be used daily so these are my options (all with printer)

kane 250 £420

v1 £530

testo £745

i use the fellas testo at work so im familiar with that, ive also used a kane but not a sprint.
also is it best to go for the v2 rather than the v1?

any helpful advice appreciated, Jim.
