I got hooked on them years ago when they were really hard to find. You still have to do a lot of searching to get some of them.
They do make offshoots and some varieties get very large whereas others stay smaller. I repot mine about every other year and divide them if they need it. They'll get tall and leggy looking eventually so you have to either trim the roots and repot the plant deeper into the soil or if it's a large variety, cut off the top portion, root and replant it and use the "stump" for producing new plants. I have to work up the nerve to whack the plant off but it has always worked on the big ones. The smaller ones I generally just repot deeper.
Here is a link to my facebook page. The album "flowers" is public so you can see it.
