Lemon Trees?

Lemon Trees?

I really want a lemon tree (and possibly a lime one as well) for my back lanai. The local nursuries either don't have lemon trees or they are very sad looking. I know someone in this community posted a couple months back about one they bought on the 'net. I've checked with a couple places online and they don't carry them. Anyone have a suggestion for a place I can order one online? Variety suggestions would also be helpful. I'm thinking a dwarf variety might be a good idea in case I ever move and want to take it with me, but my lanai has a pretty high ceiling so I could opt for a regular variety too. I'm also wondering how long it typically takes for younger trees to produce fruit. And while I'm asking questions about citrus trees, does anyone know when you should fertilize orange trees? I have 6 growing on both sides of my house, and they have a ton of oranges, but I'm wondering if it would be beneficial to fertilize them. (I live in zone 9, if anyone cares.) [ETA: I should mention I live in Florida, since for some bizarre reason I've found a few places online that won't ship trees to Florida. Bleh.]
