How limited?
The K-500 Adam suggested is about $US420. For that price, or maybe less, I would choose a demo or refurbished K-30. Or for only a little more, a new K-50.
Looks like the K-50 is being cleared out for a new model - if you can wait a couple of months it will drop below $400.
The K-30 and K-50 have a number of useful features over the K-500, like weather sealing, AF point indicator and horizon level indicator (which I find myself using a lot). They will also hold their value better than the K-500 which has not been a big seller.
One advantage of buying new is the opportunity to bundle lenses into the purchase, like the DA 35/DA 50 or DA 18-135 at heavily discounted prices. You could sell off existing lenses to help fund the bundle.
If your budget doesn't run to any of those, you might be better off keeping your K-m and spending the money on a decent lens or two. A spend of say $200-300 could get some good secondhand glass, which is a sure way to improve your pictures.
