I've never heard of them, but they look pretty competitive on pricing above 4 layers. The benefit of the budget board houses is when you need a small run of boards for prototyping. OSHPark is great when you want a few 2layer boards under say 6 sq inches. DirtyPCB is great for 2 or 4 layer boards under 15sq inches (10cmX10cm size). You can get ten 4-layer boards at 10cmX10cm for $50, where as pcbcart has that for $250
