Know nothing about ibet, but I can say a few things about the others.
FairDeal. Many are staying away because they were purchased by FiveCardCharlies who unilaterally decided to stiff one customer out of 86 dimes FD owed him. They absorbed the post-up debt of all other FD customers except him. Most consider this a sleazy move, me included, and so I eliminated them myself. I was a customer of FD for awhile, after I won a very little bit of $ in a golf contest here at MJ's, last year. I liked them okay, but this "selective pay" thing makes me not interested in them anymore, big red flag IMHO.
SIA, one of the most underrated books out there IMO. I have played with them on and off for 4 years and they have always been excellent in cust service and paid promptly w/o hassle. They let me play on credit one weekend because their cc processor was messed up, I doubt many outs would have done that for a minnow like me! Some will bash them or question them, because they will have "fav shaded" lines and many think that will "break them" in the end. I have heard this BS argument for > 4yrs, meanwhile they are going strong and have low enough limits to keep pro middlers at bay. I like them a lot for some bets ( cross sport parlays they are the absolute BEST at allowing ANY NON-CORRELATED event to be parlayed - truly ANY ). They also have low mins and cater a bit to us minnows.
WSEX. Though I am a bit po-ed that they jacked up the juice on their daily 18 hole golf matchups a few weeks ago, this is still a great out. The interactives are great and they are the first book I ever played action points and conditionals at. Their straight offerings are vanilla, but they have some unique stuff and are outstanding overall ( just wish they hadn't phucked with their 18 hole golf lines to 30 cents from 20 ). They have reasonably liberal cross sport parlay offerings. One of the "staple" outs in the industry, that most savvy bettors eventually add to their portfolio.
Since I know that you play "parlays", which I also do a lot on fb and hoops, there are a couple others u may want to consider.
ACESGOLD not only +100 for friday but true odds on parlays during the same time for NFL sides. ( I particularly like their parlay chart since a post of mine prompted them to create it 2.5 years ago! )
INFINITY 7-1 for 3 teamers 24X7.
CAMELOT Mark was allowing parlays like SIA, but lately a few props and other lines have been limited to straights only.
