For me to recommend any shop, it has to be able to deliver quickly and at a good price, including secure packaging and value P&P.
This is where I get my acrylic rod, for making flying stands.
My new source for minidrill bits and other modelling tools.
All manner of really useful materials, but especially Liquid Gravity.
Whilst pillaging old kettle filters and motorbike bits will provide some fine mesh, sometimes, it's worth going for the good stuff.
Nice Resin Kits and accessories, but also Pegasus kits and decals.
On-line modelling superstore. Even if you don't buy from here, this should be your first port of call when you want to know what is available.
A Japanese Hannants and, even taking into account P&P, prices on Japanese-made products are very, very reasonable.
My favourite shop for pre-owned kits.
My source of 1/72 instrument panel dials and Italian smoke-ring camouflage decals.
My supplier of all things Gunze, including the superlative Mr.Metalcolor paints.
My absolute favourite eBay seller.
Outstanding resin stuff, including the 1/72 pilots I'm so very fond of.
