I would recommend the Bend over Beginner: http://www.lovehoney.co.uk/product.cfm?p=809
It has two sizes of good quality silicone dildos and a little vibrating egg. I did not buy this at first, because it looked so expensive. At the time, I bought some simple jelly dildo with harness, which had a really bad chemical smell to it. Now I bought the Tantus medium size dildo and a separate vibrating harness.
