If you're looking to replicate the "clicky" feeling, you definitely will want a mechanical keyboard with either Cherry MX Blue or Cherry MX Brown switches (same switch action).
The Blues are a bit louder than the Browns but are as close to the buckling spring keyboards (i.e. IBM keyboards) in terms of feel.
You many options for these keyboards - Razer Blackwidow Ultimate, Leopold, Das Keyboard, etc. They all use the same switches but have different extras (backlighting, macro keys, etc).
I recently purchased a WASD Custom Keyboard and it's great - great design and you can customize almost everything about the keyboard. For example, here's mine:http://www.wasdkeyboards.com/custom-keyboard-designer/wasd-v1-custom-keyboard.html?kt=1&k=1&s=e5784ac77ea342ed561f03cf2d2482a8
