What's it worth (1 Viewer)

Hi
Would appreciate help in working out how much my equipment is worth, then I will put it in 'classified's' when I have learnt how to put the pictures with the words.
I have an Optricon scope ES 80 GA ED angled. Comes with lenses 40810 fixed and 40862 zoom, along with the opticron universal adaptor all comes in its own case!! Also velbon tripod.
Only selling because I have gone over to full frame camera
Appreciate your help/advice

why not look for similar used items on ebay put them in your watched folder and watch the prices they sell for ?
Devon cameras seem to still have some for sale new at £350http://www.devoncamera.co.uk/index.cfm/product/5868?utm_source=google_shopping&utm_medium=pcn&utm_term=Opticron_ES_80_v3_GA_SD_45_Fieldscope&utm_content=feed&utm_campaign=DevonCamera

I think about £450-£550 for the set up would be a reasonable asking price.
