Bear in mind it's not just materials, it's also labour time and the circuit etc. It took time to design, it takes time to make, and I imagine that a lot more care is taken in the creation of an Orange.
The Orange is in all likelyhood a better amp, I've never been dissapointed when plugging into one, that said, it's also a lot more expensive, and Laney still make a good amp. I think it's best that you play both and decide if the extra £400 is worth it, personally, I'd pay it, but that's just me. I'm young, work almost full time and still live at home, disposable income like this doesn't come around often so I'm making the most of it. If I had a nipper to feed, a mortgage to pay or a missus to buy shoes for I'd probably look at it differently. :lol:
