Annie, thank you for the link. As you say 'Swaggie' is a little on the small side, but I have contacted John and explained my situation and plans. I await his reply.
The cost of plans is a consideration, of course. But I agree that it is a fraction of the overall cost. I think the key is to find a designer who is on the same wavelength. John sounds like he might be. Jay has also been helpful but seems reluctant to move away from his suggestion, to me, to use the 'baby' badger design. It's just a bit big for my simple needs.
The Eventide is, as you say, outdated but then again...... if it ain't broke don't fix it, as the saying goes.
The search continues. I am fortunate I have time on my side.... but not the bank :)
Peter
