Decals / Transfers where do you get yours

I am in the middle of a repaint of a Ford mirage into gulf colours, looking good. the Decals I ordered from ebay have arrived and to be honest they ain't the best.
when decal dries background is white not clear, so this looks rubbish!!!
where do you get your decals from, I'm wanting decent ones in UK if poss.and water slide please. I know wraith does them and I will proberbly get from him, but would like to see others
