That's not quite fair on Fleischmann. The latest Fleischmann electric (BR 182 Taurus) can be had for £130 new from a UK shop, and there are buy-it-now new BR 146s on a certain online auction website for £90 including postage from Germany. I reckon a Fleischmannesque HST would be around £200, but it certainly wouldn't have cost Dapol anything like that much more to "go European" with the windscreen!
Here are some (fairly dire) photos of my new arrival on the track. It absolutely shouts HST at me! The directional headlights are really neatly done and DCC installation was so simple because the bodyshell comes off easily, during the course of which I noticed that part of the chassis is made from some amazingly flexible plastic which makes it even easier to dis/reassemble. I must confess I didn't actually notice anything wrong with the windscreen on the power car...perhaps I was lucky or perhaps it's just not noticeable when you put the model on a layout.
My verdict: absolutely love all aspects of the model, absolutely hate the colour discrepancy! (Which the camera definitely makes worse though.)
Perhaps Dapol can confirm, but presumably the grey on the next tranche of IC Swallow Mk3s will match the 4-car book set? According to Dapol on Facebook these are on the way in July...
