My 2 cents (I supposed you don't have cents in the UK eh?) from the USA:
Veilside was the first (and for a long time only) body kit company in the USA. By now everyone has their front bumper and/or hood. Actually I should say by now everyone has a crappy fitting, poor quality, ugly fake bumper made in Taiwan that hangs further down on the right than the left.
Now days I can get pretty much any body kit from Japan. Also, you have Do Luck, Bomex, and Top Secret officially in the USA now which gives easy access to their parts as well.
Veilside still makes the best quality parts that fit awesome and hold up very well. Just played out in the USA unfortunately.
Oh, for a good read take a look at my rant on Bomex and how far down the slope they have traveled.
