USB FDD may be useful for PCs, but not for other retro users. I have a ZX Spectrum +3 and an Amstrad CPC 6128 and an "external" 3.5 FDD, and any USB FDD won't be able to copy 180k disks (for those thing, you'll need an "authentic" FDD controller). I've been looking for a PCI FDD controller, but it seems they doesn't exist anymore (someone told me that some were manufactured in 486 - Pentium era).
I've got a PS2 to USB convertor, and I must advice to be careful when buying one of those. Not all convertors will accept UP/DOWN or LEFT/RIGHT digital buttons simultaneously. Most people won't notice that but my wife used this convertor with Stepmania and a dance mat, so it's perfectly normal to use UP and DOWN at the same time.
I've got a Thrustmaster Dual Trigger 3-in-1, and I like it because it's comforable and very robust. It's a shame that it doesn't work with XInput, and newer models from Thrustmaster (those that support XInput) doesn't look as robust as the older models.
You don't need a mainboard with LPT ports. Unless you don't have free slots, it should be easier to get a LPT/serial PCI card. I bought one of those, and it seems that can be configured for working at "legacy" ports (i.e.: 0x378).
Some other things you could be interested:
- HxC floppy emulator. I use one of those with my Spectrum +3, so I can store disk images in an SD card. It supports almost any disk scheme (that includes C64, if you've got a 1541), but the main drawback is that it plugs into a FDC (so you couldn't be able to connect it to newer computers).
- An Atari to USB convertor, for using those Competition Pros in your PC. Also, I bought a Competition Pro with USB connection.
- A PCI video card. Yes, that means PCI. I've got one ATI Rage to test boards (if I got any doubt about AGP or PCI-e video cards).
- A PCI-e to PCI convertor. Handy for that PCI video card, and it will be useful when motherboards doesn't have PCI slots (in a not-so-far future).
- CF or SD to IDE convertor. Useful with my ZX Spectrum and my divIDE, and useful with most older computers that doesn't need big hard disks. Also you could buy a SATA to IDE convertor, in case you badly need to connect a real hard disk for a computer (IDE HDDs are getting rarer).
