Replying to DSLR Camera ideas needed...

Yo guys what's up.  i was wondering if you all could give me some ideas on a descent Digital SLR camera.    I have been shooting with my '72 Pentax 35mm for the last couple years, which i love, but i am looking for a little more versatility. 

With this DSLR i want to shoot this ski season and have it be my primary camera,  in addition...i'm taking a summer long road trip all over the west and PNW, so i'll be using it then.  I was hoping to spend between $400-600. 

Thanks in advance.
