Reefmna,
I used a Rio 2500 for about two years in my tank, despite the warnings... I now use it to mix my change water... They're allright pumps IMO, but prone to a cataclysmic failure in our tanks, if/when they fail. Other pumps fail as well, however there aren't a lot of reports of other brands taking out a tank... I think part of the problem with them is the fact that they're so reasonably priced.. there's a lot of them out there. So naturally, due to law of numbers, you're going to hear about some of them (likewise, you'll never hear about a ton of people reporting what incredibly good experiences they've had with Hagen Powerheads, or anything like that...).
IMO, depending on the age of your pump, I'd let it go for a little while. Maybe put a nice Sen down on your Christmas list. If you've been really good, ask for an Eheim, now there's a good quality pump.
