i hate to use flash,but when i have to,i use the Nikon SB-28 becoz it can have more precise adjustment on the LCD.
some small flash have only full or ½ power output and usually give ard F11 for 2m @ ASA400, can't get the back ground nicely with it..
for SB or equivalent flash,u can set @ F4,or wadeva at 2m to expose the background too.
