Hey guys,

My poker game suffers when down to the final 3 and hu. Basically I have a huge amount of 3rd place finishes, some 2nd place and on rare occassions I take first but usually comes from a good run of cards. Whats the best way to practice heads up, I've tried playing the micro limits up to the $5 heads up but is usually a waist of time as I'm always up against an all in machine. Plus i don't want to invest more than $5 as I will most likely lose my investment. Any particular poker site where the players do play seriously hu at the lower limits or just anything out there that could help my lacking game?

I usually am mid stack once in the final 3 but keep getting out played.
