Have you tried Ibanez? They are known for thin necks and as well as great playability and tone. LTDs arent the only guitars for fast playing. The PRS SE series isnt too bad too. They're neck thckness is in between Fender and Ibanez. Another brand to look out for is Sterling by musicman. The AX40 and JP50 are pretty much made for fast playing and they are going for round SGD 1k. A cheaper option to Sterling would be its discontinued brother, OLP, which goes round at SGD500. I'm not sure if davis/guitar workshop still has stock of OLPs. Another brand would be Schecter, which can be found at guitar 77. Those have pretty fast necks too.
