For big go with VixSkin (either the Outlaw or the Maverick) or look at one of the offerings from Vamp Silicone (sadly not carried by Vixen). Either of these won't cost much more than what you've got there and will be 100% guaranteed safe, compatible with more lubes, easy to clean/sanitize, and will last you forever.
Tommy Gunn is the most appealing shape but I'm with everyone else on materials. I wouldn't buy any of these. It took me quite a lot of shopping and agonizing, but the only realistic one I have is the Lonestar Vixskin in chocolate and he's very pretty. (I'm also not crazy about the way the fleshy pink color looks in silicone.)
