Ok, my little story..
I've been a miggy user ever since when... a silent lurker in these forums but always hands-on active.
Left for a while because of personal things but got the Amiga bug again (again..again) about a year ago.
Decided to trick up my A2k (see avatar) and have enjoyed countless gaming/demo sessions on it. However, I got bored with seeing 'requires AGA' or 'not enough memory' when trying things on my (somewhat vast) collection of cover CD's. Especially demos! Not happy with this, a choice arose. Upgrade my A1200 or replace the A4k I sold years ago (regrets!)
Much money later, I now have (in order of purchase)-
Amiga 4000 in Micronik tower (the one with the front door) + bus board
4GB CF HDD
A3640@33mhz
3.1 Roms
Cybervision 64/3D
Now that I'm enjoying all of these colours and pixels I'm wondering what more I am missing and what more this machine has to give.
Now my question to you good people is where should I go from here?
Please bear in mind that I'm under no illusions of going on the Net with it but, really do enjoy demos and gaming.
Your suggestions are welcomed 
If you can find it, a Denab board so you can use USB devices and even boot off USB devices.
