In the past Heritage has had displays of their guitars at NAMM, so I think there's a very good chance you'll find them there.
The H 535 (similar to Gibson 335) is their flagship model. The 150 is like the les paul. And as mentioned above, high-end jazz boxes. This is the link which gives descriptions of all the different models: http://www.heritageguitar.com/indexf.html
The thing is, the guitars are hand made, with very good quality, but the cost will be about $1,000 cheaper than the mass-produced G-brand guitars. The finishes are absolutely gorgeous, and I believe, a lot of love goes into those guitars. They will also custom-make any guitar you want. Once you see them in person, you will see what I mean.
