It's just been updated so there will probably be discounts coming from Canon soon. Also if you buy from them you'll get two years warranty. Be careful with eBay sellers unless it's one of the established used dealers as it maybe a grey import. If you do go grey check their terms thoroughly. They may offer long warranties, but who is doing the repairs and where are they based? (Think Creation Watches)
A few examples from recognised used sellers here:
LCE have got them used for £899 with 6 months warranty:

For your budget you'll get some with box and accessories with less than 20,000 actuations from any of the above.
