I went to all the local bike shops last summer and wasn't impressed by any of them. I'm sure you'll have better luck in Sandy Eggo.
Down in SD I've had luck at:
Bike Bling has a big selection
Hi-Tech bikes has some knowledgeable staff and decent selection
Out of curiosity why San Diego region? It's pretty far from Palm Springs. Don's Bikes in Redlands is decent too and closer to Palm Springs. Hopefully some one else has some info to add.
Thanks for the info on that. My sister mentioned San Diego because she sometimes drives there. I'll pass on the info on Redlands! Much appreciated.
