I use lllreptile.com/ and I'm very happy with them. The crickets have always arrived in good condition and plenty of them. They give price breaks the more you buy, so for $16.99 you can get 1000, $26.99 for 2000 and so on, and this includes shipping. So for a few bucks more than what you've been spending you could be getting twice as many crickets!
They are also in California so I'd imagine it wouldn't take very long to ship them to you. The only thing is they only ship on Mondays, so you have to order by midnight on Monday or it waits until the next week. That way the insects don't get stuck in the mail over the weekend and die.
