Welcome.
What are you expecting this item to do for you? It's not the correct tool for videotape ingest/capture. It's like asking about buying a used sedan, but you want to haul a load of dirt. Or having a family of 4, and asking about a single cab 2-seater pickup.
That $100 is better spend elsewhere.
What is your realistic ideal budget, and then a max budget? Because $1000 is almost a minimum. You can attempt to cut corners, attempt to bargain hunt, but you'll still easily be at the $500 mark.
For many of us, time and sanity (ie "going bonkers") is worth more than money. It's not even a forever cost, just a temporary project cost. Buy it, use it, resell it. Quality gear holds value, junk is yours forever. With quality gear, bought from a reputable source, you'd probably already be capturing.
It's not ideael, but a non-TBC JVC S-VHS, and the ES10/15, to a known-quality capture card (certain ATI, certain Pinnacle -- not Dazzle, not GV-USB, etc), is a minimalist recipe. About $500 there. You may still have problems, as you're relying on a non-TBC frame sync, having no frame TBC in that workflow. But for 30 tapes, perhaps you can squeak by.
