I buy at $5.05 because he flashes a nice size on the ask. After I buy the nice chunk of shares, maket maker sells 54 shares at $4.89 and then another 54 shares at $4.85 trying to manipulate the price lower.
Those types of games only last so long and only the most naive of investors fall for them.
In the mean time, market maker just sells small lots of shares to lower the bid attempting to accumulate shares from weak longs that just get tired and hand them over. Personally, I don't mind paying the extra 10 or 20 cents/share knowing that when I sell the shares will be 100%+ higher.
The insider purchasing a bit higher is fine by me - if the shares were good enough for him at that price, I'll take them 5% to 10% lower.
