Photo Developing

I was wondering what people's thoughts were out there as to the best and most economical photo developers. I have read the boards and seen the horror stories about Sam's and Walmart. I currently use Walmart and have never had any trouble. I recently received something in the mail from Filmworks, formerly Seattle Filmworks. I had used them once or twice in the past and had no complaints, it just seemed high priced. Any advise and input is welcome.
Thanks

I develop all of my film by mail. I use Clark Color Lab for my APS film (to develop a roll of 25 costs $4.90, plus s&h of $1.20). That price is the same, no matter what size pictures you have on a roll. It takes about a week to get them back. I've used them for over 15 years and have no complaints. I send my 35mm film to Snapfish (check out snapfish.com) A roll of 24 costs $2.99, plus $1.99 s&h, plus they post the pictures on line....they also take about a week. I've used them for two years and think they're great too!
