I have been considering getting another hydroponic setup to accompany my aerogarden to try and grow some peppers and tomatoes over the winter (not citrus at this point though). I looked at just getting another aerogarden at first but their setups are very costly (especially upkeep) and can become problematic if you want to grow anything over a foot or two tall. I did a litte bit more searching after my last post here and found a couple of nice options that I thought I'd share.
This ebay store has good history as well as prices:

I am not quite set on any one specific setup yet but have been leaning towards this one:

I was also planning on getting this 150 watt high pressure sodium light to go overhead:

This ebay store does have many different hydro setups and packages so make sure you search through ALL of them as some of the packages have different options (the 150 wat hps light included, number of plant slots, different pumps, some include shipping, some include an airstone, some have double the nutirents, ect.).
I also plan on adding a little more lighting to the setup and found some cheap 65 watt CFLs that appear to be more than sufficient for growing plants and a bargain at $10:

I was planning on picking up 4 of those bulbs (2 for the new hydro setup and 2 more for supplemental lighting for my citrus trees) and 4 basic clamp/dome style lights:

You could obviously go cheaper but I like the bigger hood on this one and could upgrade to a 125 watt CFL with no problems.
So for give or take $180 you can have a decent sized hydro system with a 150 watt HPS light and 130 watts of CFL lighting (2 bulbs and fixtures). I really do not think you neccisarily need that much lighting but I was planning on putting a few other plants on the table with the hydro setup. The aerogarden I have (the 'classic' model) costs about $150, only puts out 50 watts of light and can only grow plants that are no more than a foot or so tall. Just something to take into consideration.
