@ BlindFarmer - I'd say you nailed it
A super convenient minor compromise - That will do most things
Although I do agree with Sea Monster - I bought one of those kits once - I think it was about £15 from B&Q (think Home Depot / bunnings) when my Wave was about £80 - It was bloody good and had a few things the Wave did not - Like a big hammer and a long measuring tape!!
Still loved and used the Wave though
