Looking

Diana 48 / 52 are great guns and very solidly built which makes buying second-hand a possible route. You'll probably want to use a scope but still look for s/h examples with the complete set of iron sights. Of the two standard calibres I prefer .22".

If you can stretch the budget slightly get a Diana 52 - its really only a more refined stock with the same action.

I hope Michael wont mind but I'll mention our good friends over at the Dianawerk Collective as being somewhere to look for an example. (A good bunch of helpful guys on there - please note its NOT one of those "hotbed of rumour" forums, so it can appear a bit quiet).
