I have a cherry ML, and used it for a short while. The key spacing is the same as any other keyboard, but a lot of the modifier keys are smaller.
Anyway, if you want a cherry MX that's like it... (I just had to get mine out and try it) I was going to say blues, but now that I've looked at it again, browns might be a better option. They aren't any more tactile, but the tactile point feels a little less mushy, and they are a lot smoother as a whole. If you liked your model M, perhaps blues are good for you, as both switches are tactile and clicky (you feel them, and they make a noise)
Perhaps a better option is to buy a new model M keyboard. They're still made, by Unicomp.

The Taobao one sort-of looks like the keycool 87, which looked pretty good, especially for the price. I don't really "do" backlit, so I can't comment further.
If you're a really hardcore FPS gamer, you shouldn't go with blues, as you can't "double tap" the switch as fast (by riding the activation point, like you can using reds). If you like typing at all, blues are really excellent for it.
