I can't find Dan Heelans list atm, but he play a fairly standard lone slann list (2x12 saurus, 3-4 skink units, 2 terradon units, 2 single sallies, engine, 1-2 scar vets, a unit of kroxigors, 1-2 units of ranked skinks and a second steg, if I recall correctly), and he is the best (or at least the highest ranked) LM player in the UK, 7th in total.
Mick Fair is an australian player who played at the austrialian masters with this list http://www.irresistibleforce.com.au/Masters/2009/MickFair.aspx , which again includes a lone Slann. He ended up 11/16 if I got my the right intel, which is still good considering the Masters is invitaional only and consists of the best players in the country. They use a pretty specific rulespack tho, so some of the standard choices are impossible to take and most players take pretty original lists.
http://baddice.co.uk/masters/the-players/tom-mawdsley/ Here we have Tom Mawdsley who played Lizardmen at the UK Masters, again a Lone Slann list. He ended up 11/16 at the tournament, which again is still a good result, especially considering the amount of Deamon players. The list is a pretty standard competative non-TG tournament list. The list is a "mundande list" tho, which means they don't tell what magic items they used (as they posted it before the tournament and obviously don't want to reveal what they have). Heelan played VC at the masters to practice for the European Team Championship so Tom was the only LM player at the event.
