Firstly Hi.
Although compacts have come a long way & in a majority of cases take shots as good as DSLR's for most (not I said most not all
), when you get down to dedicated use such as sport then Digital SLR's have the advantage. Have you considered a S/H Canon 300D or similar. Would others say a Sigma 70-300mm APO is comaparable to the top end compact lenses ? These are under £119 new from
