Justbet...

Justbet is rated B+ by sbr.  

It appears by a quick search that they are good with payouts, and don't pull too many sleazy tricks.  They seem to have the standard issue with DDOS attacks (denial of service), but this surprisingly common.

Really nice betting software.

Bad lines....well, 20cent lines.  

Been around for quite a few years.

Nice bonuses (if you are into those sorts of things)

I use instadebit, and they don't offer it.  That truly blows.  

Not sure how big of a better you are but, one free withdrawel per month, must be more than $300 to qualify for free.  To get this, you have to call in and talk to someone.

Personally, I wouldn't use them.  But, I think this gets down to what kind of a bettor you are.  I like to save 5-10% per wager by getting a better line, rather than "make" an extra few hundred bucks on sign up bonuses.  I like to click "withdraw", and have it in my instadebit account in an hour, and my bank account in 2 days.  I like books that I have heard of, and have been around forever with no issues.  

If you have any more questions, post em, or add me as a friend and PM me.
