Hi Airgirl,
When I started my PPL in 2007 I wanted a pair of DC but finances were tight and second hand ones pricey on eBay. I bought a budget pair from David Knight on eBay for around the £70.00 mark (new with free case) with a view to replacing them with DCs at a later date. After 2 years I have no complaints and will carry on with them until they give trouble and then I will treat myself to the DCs.
