I don't have a digital yet either. Being out of work for almost a year does not help the radio budget, that's for sure
I really can't say that one is 'better' than the other; much too broad a statement. Some folks like the audio of the PRO96 better than the Uniden; others like the Uniden because it can be PC controlled and has milair right out of the box (unlike the PRO96, which needs software to get that).
I'd suggest reading the comparisons in the Uniden and RS forums if you're really interested. I am not familiar with OK systems in your area and if P25 digital is even being used there. It would be an expensive toy to buy just for one trip; but if you come back here many times, perhaps it is time to investigate and make a decision.
As an aside, our little local group - the Capitol Hill Monitors - has a page of files for ARC250 users (the most popular software for the Uniden digitals) and Win96 (ditto for the PRO96/2096). So either way you go, you're covered.
You also might want to keep in mind the upcoming rebanding. The BC296 and PRO96 will, at least as is known now, either be reflashable (296) or may not need any changes at all (96). It might be tempting to buy a BC250D or 785D with the digital card. I would advise against it, since it's been mentioned that these 2 scanners will not be reflashable once rebanding takes place (they are being discontinued, actually).
73s and safe journey...Mike
