Are you asking for such service per desk or to have at least one in the office? At 1900+ for Bloomberg and 1400+ for Reuters, a firm can't afford to put it on every desk unless the trader was willing to cover a significant part of, if not all of, the cost of having the terminals. Alot of pro desks have these terminals because they are also used as trading terminals which helps offset the cost of "ownership". Since most props don't trade thru either one of these, the costs are rather high. There is a discount for added terminals, but Bloomberg doesn't kick in to around 30 terminals and Reuters until about 10 units, and then you are only getting 10% discount.
Most real 'prop' futures shops seem to have at least one, if not both reuters and bloomberg. Bucket 'pro' commission shops will have nothing.
