We've used the Tantus Maverick - it's mostly smooth so it's relative easy to insert if your gal is warmed up and you've got some good lube - I reviewed the Maverick link
My second recommendation is for a product not carried by EF - but is great because of it's unique shape. The Basix 7.5" suction cup vibe(Pipe Dream Products) link
. The 7.5" shaft has a bulbous 2" head but tapers to a more manageable 1.5" at the base. This provides the full feeling internally. One caution - since it's not silicone - it's best to use a condom with this type of toy. It can cause a burning sensation if you develop a sensitivity to the rubber.
