Welcome Back Friend.
Enjoy the Amiga as you like. Ignore the haters, avoid the beraters. Have fun.
I guess if you want to go Classic style you could go for the A1200 as it has the AGA chipset, and is one of the most hackable of the Amiga computers (ie: accelerators, controllers, storage devices, backplanes, and more.) As a nifty little bonus you can use a PCMIA networking ethernet card to get it on the internet too.
If you are lucky and are a little more ambitious with your cash, you could go big box like some of us. That meaning get you an Amiga 3000 or Amiga 4000 with accelerators and all the whipped topping that your bank account can muster up. Some of us even have the luck of having towered systems (I spent some of my money that I could have used on a Escom Amiga 4000T system on at the time new ATI Radeon 9800 Pro and a Indigo2.)
Then there are the new school options that I'm not very educated on which I'll admit, like the AmigaONE, Pegasos. I guess anyways you go LET THE GEEK BE WITH YOU. :hammer:
