I personally like Tags if you're want a cheaper Tag I would suggest the Formula1 or the Aquaracer. If you ever buy used make sure you educate yourself about it but even then its difficult esp buying online.
I would never buy watch online unless its from a very reputable store. IF ever I but it used I would first check the glass and "try" to scratch it using a key. Thats one of the easiest way to find out if its fake, I think anyways. Someone may have a different suggestion.
I'm actually looking at the Link which is very nice
