Forlorn hope for a TRS-80 Reimplementation

The eBay seller never shipped the Model III I won on eBay after 11 days, so I requested a refund. I left negative feedback (his third in a year) and he got nasty. I told him that not shipping an item that was paid for wasn't deserving of any but negative feedback. He felt that not shipping the item and refunding m money was a positive transaction... *sigh!* Model III's and 4s are selling from between $400 and $2400 on eBay. These sellers are mad. I can't say how many Model III's I saw at the old TCF flea markets for $25.00, stacked 3 or 4 deep. Wish I had bought one... My Model I is still toast, and my LNW-80 is too big and heavy to setup and use given my tiny working space. If not for the need to read/write 5.25" floppies, I'd use a small footprint PC and an emulator. The only 5.25" USB solution (http://shop.deviceside.com/prod/FC5025) is read-only, It doesn't support TRS-80 Model I/III/4 formats in any event. I enjoy seeing all these classic computer re-implementations like Vince Briel's Replica I, or the DTV C-64 joystick... I wish someone would reimplement a TRS-80 Model I/III/4 in a chip, like the DTV. There's nothing special about the Model I really, other than maybe the WDC disk controller chip. The Model III is little different, it's only the Model 4 with Hi-res graphics and such where it gets more complicated. A fellow in Australia wrote to me years ago that he was working on one, but I never heard back from him. in the early 90's there was a board that basically replaced the Model I system board and put a full Model III in the case. It was called a "Trash Compactor." I wish I had bought one on those... If anyone knows of such a project, let me know. Or, if you know of a Model I, III or 4?(preferred in reverse order) in the mid-New Jersey area available for sale or trade at a price someone on a fixed income can afford. I would have thought SOMEONE would have made a universal USB to floppy drive adapter that one could use to add a 5.25" drive (or a 3.5") like all of the ATA/SATA adapters out there. I'll keep checking eBay for a machine, I found the LNW-80 (only a Model I, not the Model II which has CP/M and 80 columns) after searching a long time. So, I haven't given up hope. Thanks!
