Hi there,
I found a StreetMachine GT in your price range on a recumbent specialist website's forum (I think it was Velo Vision) in the For Sale / Wanted section, and drove down to the Lake District to buy it.
I find it's perfect for commuting - a great height in traffic, and can carry a ton. (I have a rear pannier rack, and "lowrider" panniers which give much better handling, though inhibit aggressive turning).
Did you go and visit Ben at Kinetics?
Where abouts in Glasgow are you based?
Best,
Kenny
