I'm planning on getting a tamron 17-50 non vc before next season, but the question I have is, should I get a brand new one for £266 off amazon.com itself(not a reseller, so returning and warranty is definitely easy) or should I get a used one off ebay for around £200(although completed listings show that one sold for £160 last week) so I'm seriously considering that because of how much cheaper it is, but what would you recommend? the 5 year warranty would be great, also I've heard some people that have had to return theirs multiple times, so in another way that's making me hesitant to buy used.
