"Conical Burr Grinder" doesn't mean much and isn't a guarantee of quality. Most espresso grinders have flat burrs, anyway. For $750, you can get a Gaggia Classic and a Baratza Preciso, which will get you started. However, most people recommend a budget of $1,000 for entry-level espresso, as both the Classic and the Preciso have some drawbacks.
