Probably. If on a tight budget and was demanding a "new" instrument (which is an intolerable combination in my mind, but one you had wisely already rejected), I'd be looking for a Chinese copy of a B&S PT-10. These will be PT-10 copies, not Symphonie copies, with all that entails. But they still in my view sing better than the competition, even when they are Asian copies. But the presence of those tubas on the market has depressed prices for used instruments, which is why "probably".
Better still would be a used B&S Symphonie model, with the fully graduated bore. I've bought two of these over the years, and the most expensive one was about the price of the best Chinese clones
at the time. I don't know what it would be now, but I suspect the clones have gone up more than the used Symphonies have. Note that not all B&S Symphonie tubas are so marked. Look for the fully graduated bore, where 1, 5 and 6 have a 17mm bore rather than the 19mm bore of the PT models. The oldest of these have too short a 5th-valve branch, but that can be addressed. If you don't want to have to address it, look for one where the fifth-valve branch poked up above the upper bow by a couple of inches without being all-the-way extended.
If you just want something really cheap to learn on, look for a used four-valve F, but recognize that gigging opportunities with it will be limited because of the limited options in the lower register. And they aren't easy to find.
I also still like my Yamaha 621 for lots of things, but while those were a stunning value for what they were in 1991 they are now much more expensive, new or used.
I would probably avoid the usual suspects other than the B&S, though the rotary Willson is nice (though I don't know about intonation) and there are several very nice Miraphones, particularly the smaller models in F. These tend to be more expensive, however, so might meet your needs only if a unique buying opportunity came your way.
