The HUD argument will go either way. Use it or don"t, but don't underestimate the value of HeM to get better. The ability to look at your own play and replay hands, not to mention the 8 articles that come with it to help you understand the stats is much more valuable to a microstakes player. Either way, Hud or no Hud, get HeM.
