where to get small "starter" succulents
I can't afford to buy the beauties I see in online shops, and I don't have enough plants yet for anyone to want to trade with me (gazillions of healthy green spider plant pups, but...nothing else), so where would you suggest I find some nice, interesting, inexpensive little succulent starts to get my collection going? I have jades and common things, but I'm pretty enamored with Sedum, Haworthia, Aeonium, some Kalanchoes, less common Crassula, and so on.
Also, I really want to try my hand with some of the "living stone" species, but I've only seen them for sale as seeds, which seems an excellent way for a relative newbie to the Mesembs to become disheartened very fast. Hard enough to grow a started plant!
I'm already all over eBay, but other suggestions, or specific eBay sellers would be greatly appreciated. (I'm shamefully envious of another poster who found Haworthia, lithops, and another lovely oddity at Home Depot, of all places!)
