The rancillio silvia sounds pretty good for you. It does have a steam wand, but I think most machines will have a steam wand. Similarly any other single boiler would be a good fit, such as the Diadema Perfetta (my machine) or Isomac Zaffiro, both of which have commercial E61 group heads. I think it's a good idea to have the steam wand, in case you ever want to make coffee for anyone else, or want a hot chocolate, or a piccolo, or a macchiato etc.
Are you able to visit a sponsor to get their advice? Also nice to get some hands on experience with the machine before you purchase.
