If you wanna record guitars without an amp, and without breaking the bank, the IK Multimedia Custom Shop is one of the best routes to take as it doesn't cost anything to start.
Here's a demo of four amp samples two of which are emulations, and two that are brand built.
The custom shop also holds other VST instruments and effects.
