I have use Gibco's Select media with no problem for a number of 
years. It is a little cheaper (about 10-20%) and work well for almost
everyting we have done. Some batches of their agar had a slight
glucose contamination, not enought to grow on but enough to interfer
with chemotaxis assays. But no problem for routine stuff.
We have used Bacteriological agar from USB, which is much cheaper,
with no problems at all.
