Hello, and welcome to Amiga.org !
First, I have only AGA Amiga's right now, but I do have a soft spot for the 500. (my first Amiga, and the first computer I ever bought with my own money

)
I love the 500, but really, unless you just happen to have a 500 accelerator+RAM, and HD + interface handy, it will be cheaper / easier to go with an A1200. In particular, I've never gotten my 500 on the net, I'm sure it can be done, others may have to help with this.
I still have my Supra HD interface and original 40MB drive just in case I find a fairly cheap A500 + '030 accelerator.... I'm assuming my old MegaChip still works

My 500 setup 'back in the day' : A500, OS3.1, 2MB chip, 32 MB Fast, 2MB on HD int., CSA Derringer '030/50MHz '882/50MHz, 640MB Quantum HDD, 100MB Zip, DCTV....
Just my 2 Kronor .... (hmm, hope that's right..)
Marc
