They're both poor-quality lenses. Body-only and a 50/1.8 would be my starting-point. The 18-70DX is also surprisingly good and can be picked for about £150.
I second the 18-70 (which I have recently bought, surprisingly enough, for £150) - it doesn't have image stabilisation, which is a shame, and the zoom ring is a little stiff, but it's very sharp when stopped down and does colours very well. A good lens for the money.
