I have a canon digital rebel and a tamron 28-200 f3.8-5.6, I am looking at
buying a 2x teleconverter on eBay for under $100.



Are any brands better than others, are they bad news or should I just buy
a canon 75-300 for around $300 and not waste my money... ?

You lose two stops with the 2x converter so your tamaron with a 2x will
have a maximum aperture smaller than f/5.6 and the AF will not function.
If you want AF look at another avenue.
