you can buy replacement poles & rethread them - fairly easily or most small camping shops will do this for you.
we broke a pole within the string of 8 in the tail end of hurricane bill & the camp shop charge me £12 to repair - one new pole, new bungee cord as this had split & their labour.
it depends on whether you could do it yourself, how many are broken & the amount they are knocking off!!!
They are available quite widely but I think I'd want a give away price. Personally I'd rather buy 2nd hand complete. Plenty about - the "used once but didn't like it" type
Fibreglass poles are easy to replace, and if the tent was sound it would be a good way to get a tent on the cheap. But as they are on e-bay, and I assume not available to view, do you know the fabric is ok.
