U-matic and VHS have different needs, different workflows.
U-matic is an old broadcast form at from the 70s, and ancient rackmount TBCs from the 80s are what you may wanted here. Maybe into the 90s. It has DOC (dropout compensation), and the TBC expects the U-matic signal
VHS is a consumer format, and broadcast TBCs are extremely ineffective. That's because the VHS format is very chaotic, and has errors inherent to the format that are not expected in a broadcast format. Hence the rise of prosumer gear, with S-VHS decks and TBCs created with digital ingest/capture in mind.

Rule #1 = Understand that eBay is very often (almost always) a video dumping from in the 2020s (and was so in the late 2010s). You're not buying gear, you're gambling that it even works. That includes all the BS "tested" and "working" units. The people selling the gear are almost never qualified to judge whether it's actually working. Any image = tested, any lights on the machine = working. It's ridiculous.
Back in the 2000s, even the early 2010s, I remember when broadcast rackmotnu TBCs were in the sub-$50 range (including shipping, no tax). That ended. Those crappy ancient TBCs (for VHS, maybe not U-matic use) are now 10x+ the price.
VHS TBCs were (on average) $500 in the 2000s, dipped down a bit in the early 2010s, rebounded in the late 2010s, and then doubled in the past year or so. All the cheap TBCs you still see on eBay are often flawed units (bad Cypress aka black AVT-8710 or 1T-TBC, latter BV, etc). Sometimes I have extra TBCs in
this site's marketplace subforum, but consumer formats like VHS/S-VHS, Betamax, and Hi8/Video8 are the intended use.
Be careful. You can gamble on eBay if you wish, but broadcaster gear may be safer coming from a used broadcast store. Those have folks that (hopefully) know how to test and vet the gear. It's not just junk out of a warehouse, sold by a
Storage Wars flipper wannabe on eBay.
Timebase corrector is a wide term, and can mean anything. So if you type "time base corrector" into eBay, you're going to get all sorts of random results -- much of it outright crap.
