Aftermarket seats for 2002 Xtreme

I recently bought my Chevy S10 Xtreme and it came with different seats installed. These seats are too high and they don't slid back far enough. I want to sit lower in the truck and have enough room to get comfortable because I'm 6'4". I was hoping to hear some of your ideas on aftermarket seats Vs finding the stalk seats. I want be sure the seats I buy will fit properly in the truck. Any info or recommendation would be helpful!

Thanks
