A reference solution is most definitely very handy. I bought one for each of my hanna checkers and seachem came with one. Fairly accurate digital scales are becoming fairly cheap now and can help make your own reference solutions.
That said I believe cross checking with multiple kits is a fine way to see accuracy as most all parameters most people are looking to be in are quite ranging. For those that need more precision with accuracy will probably want to make their own solutions or even possibly reagents. Most kits have issues due to human error or manufacturing error (i.e. bad reagents).
