First, the Commodore stuff:
- PET 4032 with Datasette
- 3x VIC 20 with Datasette, 1541 (white) floppy, and 2x Mega-Cart
- C16 with Datasette
- Plus/4 with 1551 floppy
- 3x C64 with 1541 floppy
- C64C with 1541-II floppy
- C64 Executive (just because)
- 2x C128 with 2x 1571 floppy (one with JiffyDOS)
- C128D with JiffyDOS, 1581 floppy (with 1541 Ultimate II cart)
- 2x uIEC drives
- 1702 and 1902 monitors
The other 'fun' stuff I could not afford/own back then:
- 2x Atari 2600, 2600jr, and a Harmony cart
- Atari 7800
- 2x Atari 800 with 810 and 1050 floppy drives
- Tandy Color Computer 2
- TI-99/4a
... and of course my individual cartridge collection.

All of my "old" displays (monitors and TVs) are still in quite pristine condition, and I got quality video cables for composite and s/video, however, I felt compelled to purchase a new LCD monitor with every video input native to it.
Of course, most of my retro equipment either was purchased CIB, or I cobbled together the pieces to make them CIB. If a unit arrived defective, I have gotten repairs done, so all of my stuff works. Well, like me, at least for now.

The hardest part of all of the above is not the hardware/equipment, but organizing and storing all the "bulk" from cartridges, joysticks, floppies, tapes, manuals, etc. Yikes, I like the 'stuff', but the sheer mass of it all can be a little disheartening, considering most of it has been converted into digital format. Oh, I got terabytes of just about everything, too. Shameful.
IMHO, I think the Atari 7800 was the best 8-bit gaming console and C128D was the best 8-bit home computer. VIC 20 gets my kudos for being the most affordable home computer with many affordable expansions of that time, and C16 was the most underrated for all of its features @ $99.
My "modern" consoles kept are Sony PS, PS2, and original PS3.
