Hey Nicka
I have to own up, I'm the one Mary is referring to. Why am I not surprised she opted for a comercial unit after diving with me for 6 months!
Glad to hear you're enjoying the homebuilding process. It certainly can have its share of frustration too. The good news it it all becomes worth while when the system finally gets to the point where it is actually divable.
Drop me a line if you've got any questions. I may well have some bits and pieces around from my homebuild 'breather projects you'll find handy.
