Where's the best place to get spare tent poles? Got a Gelert Atlantis 4 and split two poles when setting up (entirely my fault as I decided to relocate but couldn't be bothered to dismantle the tent - crack!). Have had a look on the Gelert site, but it's £15 for a replacement kit and don't really want to spend £30 when the tent only cost me £99 new. Any bargain alternative suggestions?
