No bike that doesn't fit is a good deal or idea, IMO. Nothing ruins a ride like a bike that just doesn't quite fit. You can compensate somewhat with stems and seat posts, but that has its limits. I don't know if this is a controversial statement or not, but a mid-range quality frame that fits properly will ride & feel better than a high end frame that does not any day. Why pay top end prices if you are not going to feel the full benefit of a top end frame?

I love browsing eBay, but unless you know how you fit on a bike and can read the measurements properly it can be a dicey (and costly) prospect when you can’t throw a leg over it. That 3Rensho is a beauty (if it is the one I’ve seen), but unless you are a track rider I would pass anyway. That tube will make you feel every bump (or even ripple) that the road has to offer.
