Bigfella,
Great stand.I used Dexion racking ,and the whole thing is adjustable and can be dismantled for moving too.
The one thing you may find, if not using a CFC, is that an immersion chiller may not seem too effective.This is because of the heat retained by the burner(I think the NT/Northern guys pointed this out). I have been SLIDING the boiler to another stand(milk crate with some pavers on it) to do the chilling on
