I've used a 5D/1 for just under a year and love it! That's quite a decent price it's selling for.
or here try this 1DX 
Its an average price...
Word from a retailer is to not buy a 5d1 right now, since the 5dII was reduced in price the price reduction hasn't really filtered down to the 5D1 so within weeks/months the 5d1 will come down in price again as well.
