Spa's customer service was excellent too - I wasn't sure which size to buy so I made a special trip to Harrogate, and they didn't even ask for a credit card deposit before letting me take a test ride. I'd meant to go away and have a think but loved the test model so much I ended up ordering on the spot. All their staff knew their stuff inside out, and the main person I spoke to - Sam, I think - patiently talked me through all sorts of options on dynamos, lighting, chargers, finishing kit etc etc etc. It took something like a week to build and ship mine.
The only gripes I can come up with are tiny ones. The gears needed a bit of home fettling: as sold, it wouldn't shift easily into the big chainring or smallest rear cog, and clearances between the front mech and right-hand crank are very tight so sorting the front mech took some very careful work. As I mentioned elsewhere, the bolt holes for a bottle cage under the downtube are a little bit too low, so the supplied cage didn't fit.
And my only negative observation about Spa themselves - and this is meant as constructive criticism - is that they massively undersell their service. If you look at their website you'd probably assume that they basically sell you an off-the-peg tourer with the option of a couple of tweaks. But in fact they're building up every bike from scratch and you can spec literally everything from gear ratios to tyres to the colour of the frame decals. If I were running the business I'd build an all-singing all-dancing online bike builder, but at the very least they could have something prominent saying "yes, we will build whatever you like, give us a call".
And here is the bike, at the top of the brutal-but-beautiful ascent of Priest's Leap:
