Re the Smiths.... I have asked two different UK suppliers for a recommendation on either Smiths, Stack, etc. and neither would answer with more than two words, but that's cool. TTR400 likes the Elliot but they've unfortunately gone out of business.
I'm leaning to the Kroeber/Pitsch unit as several guys have highly recommended them. I like the look of the Scitsu but there are just too many that have had negative issues.
