Hi K.,
I really like my BOB Revolution stroller. It is pricey but very well built and geared towards serious jogging/running. It has both a fixed wheel (for safety and control while jogging) and a swivel wheel feature (for extra mobility for walking around.)
A great website is: joggingstroller.com
They have tons of user reviews and you can shop for a stroller based on specific criteria. Also if you want to save some money, there are typically lots of used jogging strollers listed on craigslist.com
good luck!
