Greetings all!

This is my first post. I only discovered aquaponics last week so please forgive the - probably - naive question.

Let's say that I wanted to build a system that I could use here in upstate NY, year round. How much would it cost? I'm sure the answer is probably, "it depends on what features you want, how much you'll do yourself, how much stuff you have laying that you can use, etc...." But, not counting the greenhouse and the heating during the winter, what's a range for the fish, tanks, plumbing, any controllers/timers, buckets, etc...? It must, even if one is very frugal, be in the $500 range for a very basic system, no?

I'm trying to read as much as I can so, perhaps, I'll chime back in with an, "oh NOW I understand ...

thanks much,
JR
