Nu Luk does a great job, but it is expensive! I got quoted £435 around a year ago (is this in line with what you were charged?)
What made you go for them over a £200 jobby from another local?
They do look very close to original colour, which is rare from what I can read of others!
It was around that mark yeah, and we've been using them for a long time, family and friends all use them too.
You have to think of it more of yes you can get them refurbished cheaper elsewhere, but for £200 extra they're powder coated and finished off like they just left the factory, and from the cheaper refurb they'll bubble in 1-2 years (happened to my brother who went to one around Stormont direction) and I'm still running some that were refurbished 4 years ago and still look factory fresh.
They're expensive but you get what you pay for definitely worth it in my opinion.
