Have had an account with Allstar for a number of years. Haven't funded it in quite some time, but never had a problem either with processing deposits and withdrawls or grading of wagers. Hope that helps a bit.
It's been awhile since I posted up funds and wagered there. If I recall correctly, I don't believe they had overnights when I used them. As for any difference with CRIS, they aren't even in the same league. CRIS is a top teir book with a long history. The first to post the most common lines on most sports of all the books. Allstar is more a second or third teir book in my opinion even though I had no problems with them at all. If you don't have an acccount with CRIS, you should.
