Ooooh. A redbay cabin, that could be the answer. Bit out of budget maybe though.
Well, done a bit of digging on the net and the Spectrum 480 is known as a Cortina 480 outside of the uk. They are built in Poland by Delphia yachts.

They also build all of the Quicksilver and some Arvor boats for Brunswick. Apparently they build about 3200 boats a year in total.
I'm still in a quandry. Interesting video of one here with a 90 bearing in mind it's rated to 60. Looks like it could be a capable little hull for its size. Half way through is better video.
I thinks a seatrial is defo in order. It would have to really impress on the water for me to swap the humber for one to be honest. Ribstuff have given me an excellent quote on an E-tec 60 though.
